Cannot listen TV while recording

[sylv]

Hi,

I am new to PVR, new to GB-PVR and new to this forum.

I just acquired a Hauppauge WinTV PVR USB2 and installation was simple and it works fine although provided s/w are limited. My intention is to shortly get an Hauppauge MediaMVP. I installed GBPVR and I am quite impressed. Congratulations for all the good work. Everything works well. I am not totally satifsfied with the live tv image quality and aspect ratio but I believe I still have to play with the settings.

That being said, I have two problems. I searched the forum for a while but can't find anything related.

1. I cannot listen TV (the recorded channel) while recording:
When I go in LiveTV while it is recording, I get the message "No tuners are available ..." and I have to choose between "Don't watch" and "Watch the program being recorded". When I select the second choice, I get a black window and it stays like that forever. Does someone has a clue what may be happening?

2. Noise when changing channel
When I watch LiveTV, there is always a sound glitch when I change channel. When I use the Hauppauge WinTV2K, channels change smoothly with no noise at all.

Finally, if I may ask, any hints on how I can enhance the liveTV image quality? The image is not as great as it is with the Hauppauge WinTV2K application.

Thanks for the help,

Sylv

reproduce the problem, then zip and attach your gbpvr.exe-native.log and I'll take a look.

I dont know.

Try switching to Overlay instead of VMR. Many video card drivers have better support for Overlay. You could also try some different video decoders.

My pvr 250 use to make noises when turning channels.. I think i updated to the newest driver on hauppauges site... It doesnt do it now..and i forgot about it till now lol! Try a differnt sound decoder also

Hi,

Thanks for your help. Regarding the playback while recording, I will reproduce and send the logs. For the audio glitch, it does not make any glitch with I use it with the Hauppauge wintv application. It makes noise only when I use the GBPVR which lets me think it is not related to the hauppauge driver. I will try other sound decoder though.

Thanks,

Sylv.

I have the same tuner wintv pvr usb2.

1. Only two fo the deinterlacing encoders will work on my setup. The others produce black screens when watching live tv(Open config, go to misc, under deinterlacing choose encoder pass thru.

2. I have the same sound glitch when changing channels, no solution yet other than to go to the tv guide, find what I want to watch and go the the channgel directly or pull the guide up on the bottom of the screen, find what I want and go to it directly.

3. The default picture is not that good on my setup. I got the best results, by going into direct.ini in gbpvr directory and changing brightness, contrast,saturation, and gain settings.

Hope this helps.

Thank you for the info. However, my setting is already at encoder pass thru.

Well, I believe I will have to live with it. :o

Ok, I will try that.

Hope this helps.

Sub: you've asked for the logs. Here they are.

Thanks again for the help.

I wanted to check the logs because this one know issue that can stop you being able to watch a video while it is still recording on some machines. I can see in the logs that your machine doesnt have this specific issue, so I dont know why you're having this problem. Sorry.

Hi Sub,

can you tell me what to look for? I get this problem intermittently and I think corresponds to some other timeshift problems where it might freeze on a program change.

Thanks.

I was looking for an error that said "FindFilterByName failed to locate filter: GB-PVR Parser", but this wont be your problem, or timeshift would never work.
