Best way to figure it out is to just plug a coax cable directly into a TV that has QAM tuner built in and auto scan for channels. Most locals (ABC, NBC, CBS, Fox, CW) are usually Clear QAM channels.

Thanks. Did one last night. Wife is not a happy camper knowing we will be without cable for a few weeks.

And just remembered. Gonna miss the Super Bowl. Crap.

Super Bowl should be on one of the networks. You can probably connect your coax to the back of your TV and at least get those few channels over QAM, or perhaps even all of your basic-tier cable channels depending on your provider.

Yes indeed! Why didn't I think of that?

You would need an OTA tuner to go along with an antenna and most likely that would need an RF connector for a feed.

Thanks, that looks pretty interesting!

Anyone else having problems picking up ABC, FOX, NBC, CBS & ESPN with their Ceton cards? I've had the card for about 2 months with no problems but on Tues I've been unable to get those channels. It says the signal is weak or nonexistent. Other channels like Fox Sport, History, CNN, Discovery works fine. All these channels are the HD ones. I live near Dallas and my cable company is Time Warner.

What is your signal strength and SNR when tuned to one of these channels?

What are "good" values for signal strength and SNR? Is the easiest method to pull them by using the MCE add-in?

Thanks.

Good signal is about -12dBmV - +12dBmV (with 0 being ideal)
With SNR, higher is better, but I'd say about 34dB is a minimum. Keep in mind they are per-channel, so have to look at them for the channels you are concerned about.

I have just built up my htpc and had some random errors. Where do I go to find these stats? Is it in the CetonTV->tuner page in 7mc? or do I have to use the Ceton program from desktop?

They are available on each of the tuners tabs (for instance, 1 --> Tuner) or also through the WMC add-in
Keep in mind they are per-frequency, and it's normal for there to be some variance.

I def need to work on signal I think, everything seems right at the edge of acceptable range..

Tuner1, chnl 113, SL:-15.3dBmV, SNR: 33.8dB
Tuner2, not tuned
Tuner3, chnl 672, SL: -14.5, SNR: 33.8dB
Tuner4, chnl 667, SL:-11.8, SNR: 34.8

The tuners are all sitting @ 54.8-55.0*C is that ok?

The temperature is fine. Signal is a bit iffy - it may be fine, but I would need to see a full diagnostic capture to say. Can you remove a splitter for testing?

Technically yes, but it would take the entire house CableTV down and wife and 2 kids might stuff me in the htpc before I could get the diagnostic done :-p

Comcast is stringent on thier signal for cable modem/phone. When they installed the phone package they pulled all my splitters and installed a Comscope SV-V2G Digital splitter (2way). One leg goes to the cable modem/phone, the other was to a 4way splitter. Since I have 7 locations I bought a 8 way splitter from Monoprice (MPT-208H) to replace the 4way that runs the rest of the house.

The 2 way is rated at -3.5dB per port
The Monoprice is listed @
Insertion Loss In Out
10.5 dB 11.5 dB 12 dB 12.5 dB
Isolation Out - Out 16 dB 18 dB 18 dB 18 dB
Return Loss In 8 dB 8 dB 8 dB 8 dB
Return Loss Out 8 dB 8 dB 8 dB 8 dB

I plan to move the htpc, once I get it to it's planned permanent location I will run a test and see what I find. Only issue I have had is a few errors overnight were it says it cannot find a tuner.

I can't speak to the Monoprice splitters specifically (I've never used their splitters, but have used other things from Monoprice) but we have found that many splitters perform poorly, and the Commscope splitters used by Comcast and Time Warner are one of the few that perform well.
In our experience, the best source for splitters is your cable company - many sold directly to customers at retail are poor.

Ceton is pretty sure this is a firmware issue, however, the have not yet released a new firmware that fixes the issue. The problem still occurs with beta 1.1.2.4.

Memory leak possibly? It'll crash when no channels are tuned and nobody is using it.

I have a feeling this issue was introduced with a previous firmware update as I don't remember having any issues initially. Possibly when they introduced the network tuner feature. Problem is, I don't have any of the older firmwares and can't find them to test.

I'm just curious if anyone else is having the same issue and noticed the same errors in the logs?

If you are getting partial recordings or the manually stopped for use by another component messages or tuner not available messages, check the CrashLog.txt in the diagnostics zip file and see if it's the same issue.

I wonder if this is the same issue that's being seen with the usb version as well.

Oh...The Infinitv card is not overheating in case you're thinking that's the issue. The temps stay under 41C on the card. It's well cooled in my system.

I really want it to be stable so I can get rid of my cable company provided HD DVR. I can't stand paying that extra $15 to $20 per month per HD DVR.

After returning the USB version and purchasing a PCIe version. I'm still having the reboot issue. And actually, the reboot issue is occuring more frequently now that I've the beta firmware installed. (although much less frequently than the USB). I had to record a 1 hour show in 3 pieces.


I suspect the same thing...it acts like a memory leak issue. It runs fine and then randomly reboots even when no one is watching TV. Admittedly, this isn't my area of expertise, but if my Tivo is recording without a hitch on the same splitter, it has to be the card or the software on it.
post #1698 of 4761
I was having trouble receiving signals form ABC, CBS, NBC & Fox. I called Time Warner to see what's wrong and the tech guy reset the signals and tried to fix it on their end. Nothing worked so they scheduled a service call for this coming Tues, Jan 7.

I decided to take my tuning adapter in & exchanged it for a different one. She gave me a brand new one and after installing it on my HTPC & calling Time Warner again to reset the signal, I am now receiving all the channels. I'm glad I did this or else I would've missed the Super Bowl tonight.
post #1699 of 4761
This restart thing is starting to get ridiculous. Pci e version. Beta firmware.

Was actually watching the sb pregame show when I thought the signal went to heck. Turns out I couldn't rewind due to the fact the tuner restarted.

We need answers. At least tell us something. Is it two weeks? A month? Or what? Every post questioning things just makes things more visible on google.

Don't get me wrong Eric,I appreciate you being a liaison with ceton.

In short we are grown ups and can handle the truth. And in all actuality being honest with outstanding issues and how you are working on them is a much better policy than ignoring them.
post #1700 of 4761
My PCIe ceton is stuttering like crazy on the super bowl. Tons of pixelation and dropped frames, lots of stutter.


Ugh, Ceton, please keep working on this.
post #1701 of 4761
So strange. Eric, are you sure all the reboot issues are firmware related? I have one of the original pci e cards on my home htpc and I have not run a windows update in over 2 years, and it's working perfectly. I keep seeing all these pci e cards that are rebooting and mine just isn't doing it. However, the USB version I got for my parents is doing it, but it was a new pc that was updated up until October of last year when I set it up.

Well, what firmware version are you running on the PCIe InfiniTV?
post #1703 of 4761
Latest non-beta firmware on the pci e, beta on the USB.

I apologize if I am hijacking this thread for a related question

Can I use non hdmi xbox 360 as media center extender? I purchased a Xbox 360 off ebay and found it does not have HDMI only Component. I am ok with lower PQ due to component, but want to be sure I will be able to watch cable TV from comcast
post #1705 of 4761
yes, xbox's without HDMI will work fine as an extender.

Well, what firmware version are you running on the PCIe InfiniTV?

I have the Infinitv USB, Motorola MTR700 TA. W7 64-bit on an old Asus M2NPV-VM with Athlon X2 4600+, 2Gb RAM.

I took a path similar to jim2100's and rafisher79's- Fresh reinstall of W7 64-bit, applied no Windows updates (did apply Cumulative WMC update from Feb 2010). I then applied the latest Ceton drivers from the website, prior to the reinstall I had applied the beta firmware linked to by Eric in a prior page of this thread hoping that it would resolve the spontaneous reboots.

I still experience the reboots, typically once or twice a day. I am not currently using this setup to record shows, only for watching live TV in the evenings, but I check the uptime of the Infinitv daily. It will reboot (according to the Diagnostics option in WMC) whether the system is in sleep mode or actively providing output during live TV. I have yet to come up with any specific pattern, it seems completely random. When it is working I have very infrequent macroblocking as noted in prior posts in this thread, other than that and the reboots the setup works very well.

It would be nice if Ceton would provide a listing of prior firmware locations (something jim2100 mentioned already) so I could experiment with those to see if the problem persists in different versions. On that note, does anyone have such a list?

Other than the question about the firmware versions I guess I just posted a "Me too" to the thread, apologies for that. Wanted to get some data points out there, see if any pattern emerges.
post #1708 of 4761
Not sure if this a Ceton problem or Windows 7, but every few days I need to reboot a client PC to get the tuner to work. If I come out of sleep it will hang at "searching for tuner" or if I try to turn the channel (because occasionally that seems to fix a blank screen) I then get "tuner unavailable."

I have had some similiar issues and find that if I open a command window as an administrator and then enter

ipconfig -release

followed by

ipconfig -renew

the issue is resolved. This is much faster than rebooting.

I asked Ceton (in a ticket I filed for the PCIe crashing problem) for PCIe firmware from Feb 2011 (or earlier), and the response was that engineering would need to check to see if they have older firmwares. I wrote back that I certainly hope Ceton has complete copies of all firmwares that have ever been released, since it would be extremely unprofessional not to (I would hope they have all the firmwares and source code in a version control system).

But that was a week ago. Ceton has not gotten back to me since then. It certainly seems like Ceton does not care about fixing their current products or helping their current customers. I guess they are completely focused on their new products, and don't care about bugs in their existing products.

If anyone downloaded PCIe InifiniTV firmware about a year ago and still has a copy saved, I'd appreciate it if you could PM me so I can get a copy of the older firmware.

By the way, if you have the USB InfiniTV, I don't know if old firmware is going to help you. While the latest firmware files can be installed on USB or PCIe InfiniTV units, I don't know if the pre-USB firmwares would install on a USB InfiniTV.
