However, the OTA video was a steady 17.50 Mbps. So if you have OTA access you're clearly better off using that for CBS than going with cable (the opposite of the situations with KQED-HD and KQEH-DT, which have better cable video than their OTA counterparts).
Hmm...I noticed that recent Comcast recording of KQEDDT programs appeared to be smaller than previous ones so I did a cable v OTA test on today's broadcast of Clifford the Big Red Dog. I discovered that the days of better Comcast KQED than OTA KQED seem to be over. frown.gif TSReader showed the OTA video PID to be over 11 Mbps, while the Comcast one was about 9 Mbps.

Has anyone noticed a huge number of NULL packets in the Comcast firewire stream starting around 4/16 or 4/17? I used to see file sizes around 5 - 6 GB/hour, but now that's up to about 16 GB/hour and it's all NULL packets. I've also had problems with MythTV getting a lock on the firewire signal because it doesn't get enough non-NULL packets before the timeout to actually get the lock.

- Has anyone else seen this? If so, has your version of Myth been able to cope with it? (I'm still running 0.24.1-5 on Fedora 14, but http://code.mythtv.org/trac/ticket/7205 hints that it's still broken in current versions.)

- If you haven't seen it, by any chance have you noticed the size of your recordings balloon by a factor of ~3?

Symptoms may include hit-and-miss recording, 0-byte recordings, an increase in firewire timeouts on recording attempts, and bloated recording sizes.

I'm down closer to San Jose, FWIW.

Howdy folks! I'm looking to get an HDHomeRun Prime and would like to get locals only in HD - can I do this with limited basic or do I need to move up to one of the digital packages? I'm guessing I also need a cablecard now that the clearqam channels are going (gone?) away?

Unfortunately I live in area that gets few if any OTA stations - so Comcast is pretty much by only option for live TV in HD.

Limited Basic works fine with CableCard and HD locals.

Analog has gone away. Clear QAM has not. If you're going with the lowest Basic subscription, you don't need a Prime, the ordinary HD Homerun tuners work just fine for the HD locals.
post #14796 of 15215
And when OpenQAM goes away so will Comcast from this house. I might as well take advantage of a U-Verse promo at that and am considering it now just to have a lower bill. HDHR would be useless with U-Verse though as would my two other QAM tuners (one USB stick and one PC card). Maybe of us have monthly "entertainment" bills that are ridiculous and no way to fully utilize. Cutting the cable looks better and better every day. I watch more Netflix than anything else anymore. Where I live there is no OTA (blocked by hills).

That's weird. I have limited basic on my account with internet, haven't used it since we moved - although I did at the old place.

I just threw a TV on and did a scan - it came back with zero channels. I thought the whole mess that Comcast has been communicating to people was that all channels were going to be encrypted.

http://customer.comcast.com/help-and-support/cable-tv/limited-basic-encryption/

Am I in an area that's already been encrypted? It sort of seems like it - or I'm getting filtered at the pole. I've only ever had the cable modem on this line, so I have not way to verify.

So if I am being encrypted can I still stick with the limited basic package and just get a cablecard for an HDHomeRun Prime?
post #14798 of 15215
did the TV you connected and scan have a QAM tuner in it? It should have picked up a number of stations, in particular the locals in HD plus their sub-channels. It's a few weeks since I used the TV in the back bedroom, but it's just a 2 year old LCD with a QAM and it got those channels. Might the difference be that I have more than just the basic package? I have digital preferred, 2 HD DVR's, 1 HD box.

Best,
jeff

I have limited basic (analog) and am able to get the HD broadcast channels in clear QAM in Santa Clara. My guess is that either there is a faulty connection somewhere in your chain, or that you are being filtered at the pole. If you've always been on limited basic, it is possible there is a notch filter out there for when everything used to be analog and they were filtering out the expanded basic channels. I'm no expert, but I know they have moved the digital channels around a bit and it is possible they have moved channels in the frequency ranges where signal is filtered out.

I think there is discussion (much) earlier in the threads, but you can call/write them and complain and they should be able to roll a truck (without a cost to you). I think I remember reading that Comcast doesn't actually have a database of where those filters got installed, so they just leave them there until someone complains.
post #14800 of 15215
If you don't have any Comcast STB or CableCard, it may be difficult to convince Comcast to come out and remove the filter. You may want to get a DTA (free) or rent a HD STB ($2.50/month) first and then tell Comcast that it does not work.
post #14801 of 15215
Just had a technician out. He pulled a filter off and now I have a whole slew of Clear QAM channels. Thanks for everyone's help!
post #14802 of 15215
They put a lot of the OpenQAM channels at frequencies that were filtered for other things. I also think their database are probably too decrepit to tell if someone still has a filter or not so they have to roll a truck which they want to avoid.

The notch filter would not kill ALL of the clear QAM signals. If he does not get any, something else is wrong.

Had that happen here when I had just Limited Basic, the block filter for Expanded also blocked the frequency KBCW was on so I had them come out and remove it.

For whatever reason, Comcast must have sent a software update to my (very basic) Motorola set-top box a few days ago. Now when I start to type in a channel number, it tells me what station is associated with that channel. For instance, when I type "167," I get, in order "XOD" (for Xfinity on Demand, channel 1), ION (channel 16), and then finally BBCW (BBC World News, channel 167).

I haven't noticed any other changes. Maybe I should check the menu for new items.
post #14806 of 15215
^ I've also noticed a change in my DCH70 channel display, so something did get updated.


But onto my real question:

Anyone having issues with KNTV 11.1 and its Cozi TV 11.2 subchannel over clear QAM on the Peninsula, specifically SM/Foster City?

For whatever reason, I've lost both KNTV and ION 65.1, and neither has been restored with a re-scan. Now that I think about it, Discovery (SD only) may be gone as well.

I've noticed in the past that the KNTV signal was weak and would disappear mid-day on some weekends, but would be fine by the time the evening came around.

Just checking before I play Comcast Phone Rep Roulette, where three different calls usually yields three different answers.


I don't watch much on NBC, but it would still be nice to have the HD version around. But by the time clear QAM disappears, so will my Comcast subscription.

I've still got Cozi TV on 11.2 in clear QAM in Rohnert Park....

They're both still 5x5 along with KKPX all on rf channel 120 here just south of you.
post #14809 of 15215
For what it's worth, I'm getting KNTV-HD on 10.1, KKPX-SD on 10.5, and Discovery-SD on 43.1 in Sunnyvale.
post #14810 of 15215
Wow! Over 2 weeks without a new post to this thread...what's up with that?

I just checked in here because it's apparent that Comcast is in the midst of a major channel shuffle on the San Mateo headend. Fair warning to QAM-tuner PVR folks.
post #14811 of 15215
I noticed over at DSL Reports that some subscribers in east coast systems are actually getting letters notifying them of specific dates when their Limited Basic channels will be encrypted.
post #14812 of 15215
As I've said before when that happens it will "bye bye Comcast". Might as well have U-Verse or maybe no local channels which I almost NEVER watch. Local should also be an option not a mandate. You can usually get about anything important on the locals over the Internet anyway and usually on the station's sites.

Sorry folks, been too busy to check in or mess with the TV...

But yeah, Comcast has torched their PSIP mapping here on the mid-Peninsula again. And KNTV and KKPX have reappeared, albeit only in SD, not HD. Cozi is blocked even on my basic box. But this issue may be isolated to my drop...


If and when Clear QAM goes away, I'm going to have some decisions to make. I'm actually OK with cutting the cord, but wish my net connection was faster.

It appears to be working its way west - our system in Springfield, IL got the encryption notice; it will be happening 6/25/13.
Also, our system just started getting HD-DTA's this month - of which I wrote a review on a couple weeks ago:

Nice writeup on the HD-DTA, and thanks for the info on the encryption transition, telcodad has started a thread over there with the so far available dates/locations.

Hi guys,
I'm still not happy with KPIX... not as bad as when we first reported it, but not up to OTA quality... Do you guys that have recording for both concur?

I haven't watched or recorded any CBS lately but I'll record a few shows tonight and see how they compare.

I just did a quick check of the KPIX stream rates OTA and here on Comcast using an HDHR tuner and they appear to be essentially the same again (as they were many moons ago, but not in April as I reported before).
post #14819 of 15215
I forgot to setup recordings last night, I'll do some tonight but per TPeterson's post above it appears they will be very similar.



In other news, noticed in a post over at DSLR that the Limited Basic encryption transition has reached the west coast.

Starting July 30, all Spokane cable TV subscribers getting Comcast’s limited basic channels will need free equipment to unscramble the signals.
post #14820 of 15215
I just did a less-quick test by recording a minute each of OTA and Comcast KPIX-DT. As back in April, the OTA sample had a video rate, per TSReader Lite, of 17.50 Mbps. The Comcast one was just under 16 Mbps--better than the measly 10-something of April, but not really equal to the stuff directly from KPIX.
