Tuning Issue (HD) with GBPVR and new HVR-1800 Card

[tiger66]

Hi all,

I recently purchased and installed an HVR-1800 card since I (finally!) realized I was getting ClearQAM channels from Comcast. I'm an old hand at the analog side of things, so no setup issues there at all. I had quite a few issues with the digital side of things, though, most of which I have worked out.

Some background: I have the latest version of GBPVR (1.3.7) installed. I have an Athlon 64 X2 6000+ processor with 2G of RAM. I'm using the on-board video (yeah, I know...) which is the Nvidia Quadro NVS 210S (basically, the 6150LE) chipset.

I know the video chipset is weak, but before you say anything, I did install WinTV 6 (not real fond of it :-)) and was able to detect and play all the HD channels without any issues. Signal was great, tuning was great, playback was very reasonable.

So - on to what I'm seeing with GBPVR. I had some issues at first with the channel scan, which after twisting some knobs and pushing some buttons (read as - I don't know what the heck I did to fix it), went away and GBPVR found all the stations. Next, I had some issues with the live preview window, which I finally attributed to the decoders I was using (I think). Once that was solved, *all* the channels showed up in the preview window - no problems. Great! I ran through all my channel mapping with the EPG data and was ready to go.

I finalized the config, dropped over to the TV Guide menu and selected one of the HD channels to view. Nothing. No video, no sound. Didn't make sense to me since the preview window was showing everything fine. Then I realized if I changed the channel up or down (up-arrow or down-arrow), the channels would come in, even the channel that was chosen from the TV Guide. This works (or doesn't work, depending on how you look at it) consistently, regardless of the channel chosen. Once I select a channel from the TV Guide, it does not seem to tune??? (no video, no audio) But as soon as I channel up or down, the tuning request to the new channel seems to work just fine. Very confusing.

Anyway, I have zipped and attached the logs. Any help would be greatly appreciated.

Any by the way - GBPVR is the best. (When you have to mess around with WinTV, you realize how great a program GBPVR really is.)

Thanks in advance!

Yeah, even BeyondTV has a hokey interface. If I could only get this darn 2250 card to tune in all the QAM it can!

tiger66, try changing <BDASubmitTuningRequestTwiceOnLivePreview> to "true" in config.xml

Make sure you use notepad and not wordpad to edit config.xml

The other things to try are setting the audio renderer back to 'system default'. You might also need to try a different audio decoder - the Intervideo NonCSS decoder you're currently using is a bit quirky.

Hi whurlston and sub,

Thanks whurlston - that fixed the problem!

I also set "BDASubmitTuningRequestTwiceOnRecord" to true since I figured that might also be a showstopper on recordings.

I then had a weird issue where the HD recordings wouldn't play, but I changed the audio decoder (Thanks sub!) and the mux selection and it started working. Very cool!

As always, I appreciate the quick and great support!

Thanks again!

What did you change the audio decoder and mux selection to?

[whurlston]

I also set "BDASubmitTuningRequestTwiceOnRecord" to true since I figured that might also be a showstopper on recordings.

Yeah, that was a good move. I think that's defaulted to true on new installs now which was why I didn't mention it. Sorry.

Well, I thought that would fix my issues, but it is already set to true. So, back to the drawing board.
