captured audio out of sync

[shun]

When I capture in DivX, the audio eventually gets out of sync. This seems to be a common problem with the capture card, the Leadtek WinFast TV2000 XP. Anyone knows if this is solvable? My computer is an AthlonXP 1800+ with 512mb DDR.

Well, someone suggested to me that this is due to the computer not being fast enought o handle both video and audion compressions in real time.

Does anyone have a computer fast enough to compress using things like DivX and mp3 at the same time?

Nobody has. Since divx requaries alot of CPU power it might be able to realtime compress using a p4 3.03GHz.
I red a lot of posts where people try to compress audio in realtime, and usually this results in bad synch.
So my suggestion is to capture using uncompressed PCM sound for the audio and Huffyuv for the video. The video will look much better, but the bad thing is that it would require about 30GB/hour if you capture at 768*576

Thanks for the clarification. I think being able to sufficiently compress both video and audio in real time would be great for PVR purposes -- I think it should be a requirement. To me, DivX and mp3 are the perfect combination, it's a shame that this is difficult to do in real time. That's something for me to look forward to when upgrading my hardware next time.

I use Morgan Mjpeg video-capture-codec, and PCM audio capture, and still audio ius out of synch. There are other problems here I think. Some says, the video, and audio capture HW runs on different clock-synch.
My problem, the captured avi is fine, if I DivX it with virtualDub is fine, but when I MPG it with TMPGenc (for example) the mpg file audio is out of synch!
Anybody has any comments ????

Thanks.
