I recently purchased this TV

Magnavox 32” Digital LCD HDTV with ATSC/QAM Tuner model - 32MF337B_27

I went so far as to attach it directly to the drop from cabelvision and still have a problem.

This TV will not pick up the standard HD channels that my other TV's get. 2.1, 4.1, 5.1...etc My envision and westinghouse do not have this issue. I thought it was a signal strength issue which is why I connected it to the drop. Still no luck. It does get 84 digital channels and I can tune many from 21.4 on but none of the national channels except it only gets 7.1, 7.2 and 7.3 in the 2-13 channel range

It is really odd. Any ideas?

What are the real QAM channel numbers? You need to tune to them.

It is really odd. Any ideas?If your other HDTV's get the same digital channels, and you tried the same drops as they use, it is a problem with the QAM tuner in the Magnavox. You could try exchanging it, but it will probably have the same problem.

Some QAM tuners simply do not work correctly. I don't know specifically about the Magnavox, but if 2 other sets get the channels and the Magnavox doesn't, it's pretty clear where the problem is.

What are the real QAM channel numbers? You need to tune to them.

Ed

Some cableco's assign the analog channel numbers to the local HD QAM channels, others put them on the same HD channel numbers as they are assigned on a HD cable box, others do not make any assignment and they can be anywhere on QAM up to 135.

For example, in Michigan:

WOW puts local HD ABC on QAM channel 200, the same as what their HD cable box would show.

Charter puts local HD on the same channel as what an ATSC tuner would remap to, 7-1.

Comcast also uses the ATSC tuner remap numbers, but changes the QAM location on somewhat of a regular basis, requiring end users to rescan for local HD channels.

The Magnavox does not have the option of manual tunning so if the autotune does not pick it up I can not just type in 2.1 and have it find the channel.

Cablevision assigns X.1 to the local version of the HD channels. Like I had said 2 in HD is 2.1...the other TV's pick this up fine.

I already called Magnavox and as I am under warranty I have to take it to a "local" service center. I wonder if this is even a repairable thing....

Thanks for the advice so far.

Your cable line has both analog channels 2-76 on it and digital channels on it.
I suggest that you insure that you are getting the proper tunning using an antenna first for both NTSC analog and ATSC digital.
Then when you switch to cable supplying both tuners you should get the cable analog chanels and the unencrypted QAM digital channels.
Are your other TVs just using an antenna with an ATSC only digital tuner?

WOW puts local HD ABC on QAM channel 200, the same as what their HD cable box would show.
But QAM tops out at channel 135. :confused:

All my TV's are using the built in tuners, they all have NTSC, ATSC and QAM via cable from cablevision. I would think that if 2 of my TV's can located the channels at 2.1, 4.1, 5.1....that the MAG should be doing the same.

Are you suggesting I try to use an external antenna? I am not sure I have one and do not want to spend significant $$$ on one (over $20).

Thanks

It has a Funai tuner, and those seem to have a problem picking up all the channels.

The Magnavox, Philips and Toshiba DVD recorders with QAM tuners all have that tendency, too.

Somtimes exchanging it may help, but often you'll still pick up different channels, yet still not all of them.

When you stated that you were getting over 80 digital channels in addition to whatever analog cable channels your TV is receiving I assumed that you had an antenna. Apparently your cable provider is supplying a lot more digital channels using unencrypted QAM then other cable providers. Normally they only provide a dozen or less since they are only required to support one sub-channel from each local digital broadcaster and provide it unencrypted.

I certainly don't expect you to invest in an antenna since you are not using one.

Is it possible that your signal strength to the new TV is either too weak or too strong for the digital tuner?

Is it possible that your signal strength to the new TV is either too weak or too strong for the digital tuner?

I doubt it, I tried it hooked up directly to the drop as well as on various split locations....

Weak "Funai" tuner huh? Never heard of it....I will do some research

But QAM tops out at channel 135. :confused:

EdThe cableco re-maps them to the other numbers.

That is the issue, and like I said, an exchange will probably not help.

He is already getting the QAM channels from the cableco fine on two other sets. An antenna is not the issue. Signal strength is not the issue.

I allrady comented on the antenna issue.
Since you stated that the "funai" tuner was weak I apparently misuderstood that to meant thay it required stronger signal strength to recieve more available channels. What did you mean by "weak" instead?

Like I said, some QAM tuners simply do not work correctly. This is a known issue, starting a long time ago, with one of the older Samsung DTV / QAM tuners that only went up to 125. Others don't pick up all available QAM channels.

Ok i was not aware that you meant that the funai tuners did not work even though they are highly rated in some reviews other reviews that you are aware state that they do not work well at all.

The cableco re-maps them to the other numbers.
Yes, I know that. But you were saying QAM channel 200 NOT remapped.

Ed

Yes, I know that. But you were saying QAM channel 200 NOT remapped.

EdLet me try again. The cableco takes the ATSC channel, decodes it, puts it on the QAM channel they want, then remaps it to the channel location they want.

So, here's the way WOW does it:

Receive WXYZ-DT, UHF channel 41, PSIP channel 7. Decode it. Assign it to QAM channel xxx. Remap QAM channel xxx to channel 200.

Northjerseyguy,
What is your City and Zipcode. I would like to check out the digital channel information at their Website.
It is unusual for any cable company to support other then the -1 or .1 subchannel from any local broadcaster since the FCC does not require them to provide more then one subchannel. Also it is unusual for any cable provider not to encrypt all channels other then those from the Local Broadcasters.
I live in Southern California and my cable provider supplies less then 10 digital channels in Unencrypted QAM and none of those are for other then -1 subchannels.
Are either of you other TVs using a cable card with their internal tuners?

I'm in central NJ and my Comcast Cable has loads of unencrypted digital channels. They include all the broadcast subchannels and maybe even some non-broadcast channels.

OK. And what I was saying to the OP, was that you need to try tuning the QAM receiver to xxx and not 7.1.

EdIn most all cases, you can't actually tune to a QAM channel. You can only tune to the channel the cableco remaps the QAM channel to. (in this case, the only channels he can get are auto scanned, there is no manual additions)

The exception is if the cableco doesn't assign a channel number, then the QAM number becomes the channel number, which is rare. Almost always, the cableco like to put the local HD channels in QAM in specific places, grouped together.

The alias remapping such as remapping channel 7-1 which might me be on QAM channel 125 to channel 200 on one cable system and to 701 on another cable system is done by the program guide provided on the cable companies digital STB.
Servcies such as antenna.web, titanTV.com and Zap2It supply the channel alias that is suypplied by the broadcaster in its OTA broadcast such as 7-1 and this is what a ATSC tuner or QAM tuner will find on a search since it does not receive the EPG of the cable company in the case of QAM broadcasts.

Wild guess. At first you tried an antenna, but the TV was in the CATV mode, so it didn't even look for the OTA channels because they are on UHF.

Next you connected it to cable but there is a second, unrelated problem.

The alias remapping such as remapping channel 7-1 which might me be on QAM channel 125 to channel 200 on one cable system and to 701 on another cable system is done by the program guide provided on the cable companies digital STB.For the cable boxes, yes. But not for clear QAM channels.

Let's take this point by point as this thread has gotten so convulted


Magnavox 32” Digital LCD HDTV with ATSC/QAM Tuner model - 32MF337B_27

I went so far as to attach it directly to the drop from cabelvision and still have a problem.

This TV will not pick up the standard HD channels that my other TV's get. 2.1, 4.1, 5.1...etc



Those Channel numbers are ATSC OTA designation and have nothing to do with Cablevision. 2.1 = WCBS-DT 4.1=WNBC-DT 5.1=WNYW-DT etc. Cablevision puts WCBS-DT at 702, WNBC-DT at 704, WYNW-DT at 705 and WABC-DT at 707.

As you have specifically said, 2.1, 4.1, 5.1 and 7.1, you are not speaking of Cablevision - but OTA ATSC stations. This has NOTHING to do with a QAM tuner.


My envision and westinghouse do not have this issue. I thought it was a signal strength issue which is why I connected it to the drop. Still no luck. It does get 84 digital channels and I can tune many from 21.4 on but none of the national channels except it only gets 7.1, 7.2 and 7.3 in the 2-13 channel range


Again, that is OTA. There is a reason why you are not getting these if connected to Cablevision.

Furthermore, is your TV searching to receive Cable Channels 14+ or UHF channels 14+ as they are not the same frequency.

Clearly, the TV in question is not picking up the channel mapping provided by the Cable Company. If it were, 7.1 would be be technically on something like 110.130 or 97.110 and remapped to Channel 707, but clearly the Magnavox is not remapping the channel.


If your other HDTV's get the same digital channels, and you tried the same drops as they use, it is a problem with the QAM tuner in the Magnavox. You could try exchanging it, but it will probably have the same problem.

Some QAM tuners simply do not work correctly. I don't know specifically about the Magnavox, but if 2 other sets get the channels and the Magnavox doesn't, it's pretty clear where the problem is.


In the example given by the OP, he lists ATSC channels, not QAM channels. It has nothing to do with the QAM channels. If it were, his QAM channels of the networks would be either listed between 702-713 or at the exact QAM frequency of something like 91.610 or 114.700 - not 2.1 or 7.1.

Not really sure what you guys are discussing but I tried the OTA channels. My tuner when set to Antenna vs cable will get channel 2.1 but when I plug in my coax from my cable co and scan via the cable tuner mode....no channel 2.1....it is making me thing this tuner is a bit funky....

Cable co is coming out to check my signal next week but I have a feeling that will not help.

As far as the mapping goes, all my TV's get the channels this way. The channels I noted of 2.1, 4.1...etc are the HD versions of 2 and 4...etc so I have no idea what this has to do with it.

I think you are missing the basic point here. When you set to antenna, you are receiving 2.1 OTA. When you set to cable, your cable company is sending out the signal for that particular station not on channel 2.1, but on a different channel designation - one of the other posters suggested it might be on channel 702.

Northjerseyguy,
Again I ask what city and Zip code are you located it.

The name of the channel that is broadcast as part of the digital broadcast is not the same as the FCC channel frequency that it is being broadast over. Cable and satellite STBs use aliass(such as 200 or 702) for the channel name.
So Digital Channel 2 has names such as 2-1, 2-2 etc even when it is being broadcast on OTA channel 45 or QAM channel 125 which is why an ATSC tuner or QAM tuner scan 2-1 will show up.

In the example given by the OP, he lists ATSC channels, not QAM channels. It has nothing to do with the QAM channels. If it were, his QAM channels of the networks would be either listed between 702-713 or at the exact QAM frequency of something like 91.610 or 114.700 - not 2.1 or 7.1.You are missing the point. It has everything to do with ATSC channel numbers, based on his comment that he has two other HDTV's that are getting local HD from CV in QAM, on the ATSC numbers.

Cableco's can, and do, reassign QAM channels to ATSC channel numbers.

Not having CV as a provider, I don't know what their policy is, but there are 3 possibilities:

- They assign the QAM channel, and do no remapping.
- They assign the QAM channel, and remap to the ATSC number.
- They assign the QAM channel, and remap to a location of their choosing.

None of this is directly related to the cable box channel number.

With all due respect, you are missing the point - not me.

I know Cableco's can and do reassign QAM channels to ANY CHANNEL of their choosing.

As noted above in my other post, CV remaps those to channels 702, 704, 705, 707 etc - not 2.1, 4.1, 5.1 or 7.1 on their system.

The only two possible channels that will show up on a CV system are the remapped 700s or the original QAM Channel number - nothing in single digits - unless you are talking about the NTSC analog broadcast.

The bottom line is the OP either:

1) Has no idea where his signal is coming from

or

2) used the 2.1, 4.1, 5.1, 7.1 etc so those away from the market, such as yourself, would understand he was talking about the same programming that is seen on the main digital channel of the OTA stations - and not what channel numbers are actually showing up as on his TV.

Bottom line - if he IS getting WCBS-DT as 2.1 on his TV, its not coming from CV. If he is getting it as 702 or a higher QAM number with decimals, then it is from CV.

I know Cableco's can and do reassign QAM channels to ANY CHANNEL of their choosing.

As noted above in my other post, CV remaps those to channels 702, 704, 705, 707 etc - not 2.1, 4.1, 5.1 or 7.1 on their system.Is that REALLY TRUE for QAM tuners? I know that what you are saying is true for set top boxes where cable downloads a channel map pointing to the appropriate QAM channel when a given channel (such as 702) is tuned on the STB.

But I don't believe that those maps exist in the basic TV's that have Clear QAM tuners. In those cases, I've understood that either the TV will tune something like 123-2 or 123.2 (QAM channel 123, bitstream 2) or IF cable passes the PSIP (a current point in consideration at the FCC as most do not) AND the TV decodes the PSIP from the QAM tuner then the original designation (2.1 or 2-1) would be displayed.

With all due respect, you are missing the point - not me.

Please confirm.

That being the case, I agree your two possibilities cover the situation.

And again, getting back to the OP's issue, if he has two existing sets with QAM tuners that are getting local HD from CV, the problem is with the new set. Same would apply if he was using an antenna.

Is that REALLY TRUE for QAM tuners?.Yes, but it's not really a tuner issue, it's how the cableco assigns the locations.

Again, the cableco can:
- Assign the QAM channel, and do no remapping.
- Assign the QAM channel, and remap to the ATSC number.
- Assign the QAM channel, and remap to a location of their choosing.

I think you are missing the basic point here. When you set to antenna, you are receiving 2.1 OTA. When you set to cable, your cable company is sending out the signal for that particular station not on channel 2.1, but on a different channel designation - one of the other posters suggested it might be on channel 702.


No I do not think so. All my other HD Tv's get the channel at 2.1 with their built in tuners so I would expect this TV to do the same. I was just commenting that it got OTA 2.1 (same broadcast as 2.1 via cable) so it is not an issue with the TV not being able to get the channel number itself. I understand the difference.

Since you still have not provided your location I am still unable to confirm from your cable comany that they are providing the about 80 channels of unencrypted QAM digital channels that you say you get on the other TVs. Do you possibly mean that your are getting 80 channels on the other TVs some of which are unencrypted QAM channels as indicated by their channel numbers being of the form X-1, X-2, X-3, Y-1, Y-2 etc?

All my other HD Tv's get the channel at 2.1 with their built in tuners Do you know for a fact that the other TVs get it on QAM channel 2.1 (and how do you know?), or is it simply the TVs displaying a "2.1" (which I think is the more likly case)?

Ed

The other TVs are getting the digital channel whose name is 2-1 from the PSIP information in the QAM channel being received. The actual QAM channel being used is not displayed.

I am in the morristown, nj area for cablevision.

I am saying it is channel 2.1 because all of the other TV's are showing it as 2.1 on their displays and when I check the channel list of ones that were auto scanned and confirmed that is what I see. If they are remapping it I do not see it. If I had a cable box from CV then I believe I would see it as 702.

Yes this is what I think the case is and I do not understand why the 2 other TV's get different channels. Where would you confirm this?

I do think that there is a problem with the tuner in your new TV and If I had your city and Zip code I could go to your Cable companie's Website, Zap2It.com and probaby antennaweb.org to find out exactly what unencrypted QAM channels are over your cable line since you are not using a STB or a cable card with the other TV's

Morristown 07960

Well, based on the manual for the 32MF337B on page 12 of the Autoprogram it says that. In Antenna mode the does NTSC and ATSC, Where when Cable is selected QAM is used.So, if an auto program was already done to see OTA signals. Then you would have to have it connected to the cable and autoprogram in cable mode.

http://www.p4c.philips.com/files/3/32mf337b_27/32mf337b_27_dfu_aen.pdf

According to Zap2it.com analog channel 14 has your TV guide on it and and it appears that the you have 100 digital channels starting at channel 100 in the guide.

http://tvlistings.zap2it.com/tvlistings/ZCGrid.do?zipcode=07960

I could not find any information to say what the real digital channel names for the digital channel.

According to the following press release you have lots of "free" SD and HD digital channels available as long as you have digital cable box from cable vision.

It is my opinion that cablevision is not encrypting any of its standard SD or "free" HD digital channels which is why the QAM tuners on the TVs are receiving them.

Why the QAM tuner on your TV is not receiving them I do not know. Hopefully the Autoprogram setting referred to by capttylor is the answer.

. . .I could go to your Cable companie's Website, cable companies have no interest in telling you what their QAM channel line-ups are
Zap2It.com don't know this site but the link you gave doesn't seem to have any real useful info
and probaby antennaweb.org to find out exactly what unencrypted QAM channels are over your cable line this site is not going to have any cable company QAM info.

I think your best bet is to ask at the forum thread for your location. My guess is that the channels are there - but you need to find them.

Ed

Since you've not included your location, I'll have to assume you have CV, or know someone that does, and know the local HD channel numbers that a QAM tuner would pick up. Please confirm.

That being the case, I agree your two possibilities cover the situation.


Out on the Island, getting the channel information exactly as I stated.

However, I wanted to check out a hunch and asked AVSer Joseph Dubin who has one of the same TVs I do, but lives in the Bronx in a totally digital area to run a scan himself.

He reports he IS getting the PSIP info with proper 2.1, 4.1, 7.1 etc channel info in his area which is a newer upgraded area on a set identical to mine - only difference is area and a newer/higher bandwidth/Non-SDV area.

Now, I agree that should have no bearing on the way this is handled, but for whatever reason, the answer to what Cablevision is putting in the PSIP data seems to depend on the area you are in.

I posted the first link just to show that analog channel 14 had the cablevision guide listing for his local cablevision service so the OP could find out what digital channels were available using the digital channel number alias numbers used by cablevision starting an channel 100 if he had the cablevision digital tuner STB.

I foregot to post the second link and here it is:

http://www.cablevision.com/about/news/article.jsp?d=070208

Now, I agree that should have no bearing on the way this is handled, but for whatever reason, the answer to what Cablevision is putting in the PSIP data seems to depend on the area you are in.The FCC has not (yet) required that cable pass on PSIP data. Apparently some systems (such as the OPs) do pass it, while others (probably the majority do not). Because it has not been a requirement, I suspect that many TV manufacturers did not decode the PSIP from the QAM tuner (but did from the ATSC tuner) - hence two of his sets show PSIP data (2.1, etc.) Where PSIP data does not exist, sets typically display the QAM channel and bitstream locator, such as 123-2. The OP should be able to get WCBS HD and others on his set - but they may show up differently.

It is my opinion that cablevision is not encrypting any of its standard SD or "free" HD digital channels which is why the QAM tuners on the TVs are receiving them.That's not typically the case. These HD channels are "free" to those already subscribing to their digital service. That does not mean that these channels are not encrypted - it means that they provide decryption to those with their boxes.

FCC regulations do not allow cable to encrypt the HD signals from the local OTA HD stations that they carry - but those regs do not apply to things like Discovery HD Theater and CNN HD. Bottom line: he should be able to receive the local HD channels on his QAM tuner, but not necessarily the other "free" HD channels that CableVision is talking about.

Since the OP stated he was getting about 80 diital channels with their PSIP names indicatd scanning with the clearQAM tuner on two of his TVs CableVision is not following the normal case. I am sure that Cablevision will upgrade their digtial service in the future to include encryption. CableVision to be a regional cable provider and may not yet have had the funds to supply encrypted digital. There is no mention of any subscription services on their website and stated in the news release you just need their digital (QAM) tuner to receive any of their digital channels.
There is only one local OTA digital channel available at the OP's location and it is a PBS station located 18 miles away in New Brunswick New Jersey.

Since the OP stated he was getting about 80 diital channels with their PSIP names indicatd scanning with the clearQAM tuner on two of his TVs CableVision is not following the normal case.Yeh, I missed the part about 80 channels (unless most of those channels are "junk"). I just wanted to point out that having channels available for "free" to digital tier customers does not indicate that they are not encrypted. I am sure that Cablevision will upgrade their digtial service in the future to include encryption. CableVision to be a regional cable provider and may not yet have had the funds to supply encrypted digital.It's not an issue of funds: encryption ability is basically built-into the QAM modulators that they obviously have.
There is no mention of any subscription services on their website and stated in the news release you just need their digital (QAM) tuner to receive any of their digital channels.They referred to "15 new free high-definition channels to iO TV digital cable customers". That certainly is a "subscription service" (the press release later talks about 85% of their customers subscribe to that - a pretty high number).
There is only one local OTA digital channel available at the OP's location and it is a PBS station located 18 miles away in New Brunswick New Jersey.The OP is clearly in the NYC DMA area so those network stations are "local".

The OP stated that he lives in Morristown N.Y Zip code 07960 AntennaWeb.org stated that although he is 25 miles from NewYork City he casn only get analog channels from NYC.
I totally agree with you it I could not believe that all of the digital channels were being tranmitted unencrypted and doubted what the OP was saying was fact. However, It is the only explanation I can come up with based on his clearQAM reception of 80 channels.
I also agree that stating they were free to digital tier customers/customers with digitla STBs certainly did not imply that they were unencrypted. For my cable provider "Free" to digital cable service customers means they are encrypted.
If you have a more logical explanation of how is getting all of the unencrypted channels a I look forward to your explanation.
Maybe the OP will tell of us if he gets all of the good HD channels or just poor quality SD digital ones and if he subscribes to iO TV digital cable service since it appeared to me that all that ment was that they issued him digital cable STBs.

One thought on his problem: If he is getting HD channels on the QAM tuners on two TVs that he is not getting on his Magnavox it could be that he has a splitter (or even a surge supressor) in the line for the Magnavox that is not passing the higher frequencies. Any splitter should be rated for AT LEAST 1GHz, and there should be no surge supressor in the line (they can really screw things up at the higher QAM channels).

He tried the new set on both other drops, that are already proven with the other sets.

He tried the new set on both other drops, that are already proven with the other sets.Did he do a re-scan (on "Cable") at those other drops? If he didn't, he would only be able to tune the stations that he "learned" on the first drop.

The FCC has not (yet) required that cable pass on PSIP data. Apparently some systems (such as the OPs) do pass it, while others (probably the majority do not).


Again, as I stated in my post you are referring to, we are both on the NY Area CV System


Because it has not been a requirement, I suspect that many TV manufacturers did not decode the PSIP from the QAM tuner (but did from the ATSC tuner) - hence two of his sets show PSIP data (2.1, etc.)



Also as stated, I had a specific CV sub and AVS Member who is on CV in the Bronx with THE SAME TYPE OF SONY QAM TV as myself bypass the STB and do a scan to see how HIS TV picks up the PSIP info. As noted, he is on the upgraded digital system that DOES NOT use SDV. Thus, its not a difference in TV models that is causing this issue.


Where PSIP data does not exist, sets typically display the QAM channel and bitstream locator, such as 123-2. The OP should be able to get WCBS HD and others on his set - but they may show up differently.

No one ever disputed that fact.

BeachComber,

Sorry, I was not trying to debate your post - I was simply expanding on your observation in that post.

However, there was an earlier post (http://www.avsforum.com/avs-vb/showthread.php?p=14281874#post14281874) where I did question your statement about re-mapping to the 700's in clear QAM TVs. My question remains unanswered.

http://www.avsforum.com/avs-vb/showpost.php?p=14290937&postcount=37Ken, What I am (and did) specifically ask is were clear QAM sets capable of the mapping function being discussed? I do not believe that any are. While your response absolutely does apply to STBs, I have not seen a clear QAM set that had such mapping capability. If there is, I'd sure like to know what it is.

My tuner when set to Antenna vs cable will get channel 2.1 but when I plug in my coax from my cable co and scan via the cable tuner mode....no channel 2.1....it is making me thing this tuner is a bit funky....
and I am saying it is channel 2.1 because all of the other TV's are showing it as 2.1 on their displays and when I check the channel list of ones that were auto scanned and confirmed that is what I see.I'm trying to do 2 things here:
Help resolve his problem.
Understand the issue about clear QAM operation (hence my pushing on the cableco remap).
On helping resolve the problem, I suspect that the drop he tried (and did his scan on) is somehow not passing the QAM channels with sufficient strength. So they are not learned on that set. Then he takes that set and connects it to the other outlets and finds that the channels are not showing up either - not realizing that these channels were not learned at the first location and thus could not be tuned at the other locations. If he did this rescan (on cable) at these known good drops then it would help if he specfically said so.

Of course, the other possibility - that has been discussed quite a bit, but never fully settled, is that his MAG does not decode the PSIP from cable and that the 2.1 that he is looking for shows up as (something like) 123-2 (the actual QAM channel) and that he hasn't sorted through all the digital channels he said he got to find them.

CV is playing with the PSIP DataFrom those posts, it looks only like the PSIP is getting passed through or not. No "remapping". Either it is 4.1 (or whatever the PSIP designator is) or the actual QAM channel (84.5). None of those talk about something like 704, which is real re-mapping and I believe is done only in STBs.

Well, if you want to get technical about it, WCBS-DT is not on Channel 2 and WNBC-DT is not on Channel 4, but they are remapped to 2.1 and 4.1 - so yes, THEY ARE BEING REMAPPED.

Remapping is nothing more than moving a channel from its physical channel to its virtual channel.

Whatever,

How is the OP doing with HIS problem?

Ken, What I am (and did) specifically ask is were clear QAM sets capable of the mapping function being discussed?No. Clear QAM tuners can only receive the channel where it's placed by the cableco, which again can be in one of the three places I mentioned above.

Whatever,

Haven't heard, but I'd bet he's returning the Magnavox.

From those posts, it looks only like the PSIP is getting passed through or not. No "remapping"..Due to how QAM processing works (everything has to be stripped off the bitstream), cableco's don't 'pass' PSIP from the ATSC station. It always has to be remapped.

None of those talk about something like 704, which is real re-mapping and I believe is done only in STBs.Once more, where a local HD channel shows up on a QAM tuner is solely based on where the cableco assigns it:
- Assign the QAM channel, and do no remapping. This would typcially be a number somewhere in the 100-135 range, like 122.2.
- Assign the QAM channel, and remap to the ATSC number. This would typcially be 2 through 69-1, -2, etc.
- Assign the QAM channel, and remap to a location of their choosing. This could be anywhere, including 704, etc.

I have wow cable(no cable box),samsung-LN54096D,LCD.
All channels work ok but when iam channeling-up 36,37,38,39, once i get to 39 ( there nothing on 39) and ch-up it goes 39-350,39-351,39-352,and so on.Did rescan does not change anything. Any way to fix this,would appriciate any help. THANKS
