Hauppauge PVR-500 MCE - gbpvr encoding problems

[mvalenci]

GBPVR seems a very nice peice of software and it looks like it supports my Hauppauge PVR-500-MCE.
However I have some quality issues with recorded TV - the MPEG stream is very bumpy and frames looks out of synch (when picture has motion).

The Recording Plugin is "Direct Recording Plugin" with "Hauppauge PVR 500 with FM tuner".
The Meduum Quality settings are:
- NTSC 480x480 / PAL 480x576 --> is there a way to verify I'm in PAL mode ?
- CBR, 3500Kbps
- Audio 224 (bit rate), 48Khz

I have noticed some people discuss the encoder settings when these problems appear, but as a technical person that still has got to learn alot in the PVR world, I can't tell how this is related to the *encoding* settings of this card.
When the card produces a stream to be saved to an mpeg file, it already prepares the stream with the configured settings. the *decoder* seem to be used only during playback - am I missing something ?!

If my assumptions are right, the decoder has little affect about the quality of the stream. I try to use many softwares to play the MPEG file (inclugind PowerDVD, but the quality stays the same - jumpy and irritating)

please let me know if you can diagnose the problem. and find the problem.

Given your description, I would guess you've got the problem with the version of quartz.dll. See http://forums.nextpvr.com/showthread.php?t=5600

If you open the mpg in virtualdubmod, it will display the exact frame size, and framerate.
Click file, File Information.

The problem was identified...
It seems like my both machines were using the same MPEG2 decoder (Nvidia Personal Cinema). it looks like this decoder does not handle the stream which is made by Huppauge PVR-500 very well.
If gbpvr is not responsibole in any way to the MPEG2 stream file (even not the headers) than once again, it is rock solid and a very nice peice of art.

note: can someone clarify if the MPEG2 headers are created by GBPVR or by the Hardware ?

thanks

The MPEG2 file is solely the responsibility of the hardware and it's drivers. GBPVR may initiate the recording process, but it's the drivers that do that work. It also does not play the video itself, but relies on DirectShow and the decoder you've configured it to use.

GB-PVR doesnt write anything to the file itself. It writes the data byte for byte as generated card. It doesnt even look at the data.
