Having trouble getting VirtualDub 1.4.10 to sync audio and video correctly :(

[NFS4]

I've been recording some TV shows using my Hauppage TV tuner and PowerVCR II. The good thing is that once it records the show in MPEG-1 format, I can play it back in Windows Media Player and the video and audio are synced perfectly from start to finish no matter what.

But when I use VirtualDub to make a DIVX rip of the clip (I've tried all different bitrates and tried messing around with the audio offset +/- millseconds) and I still can't get it to sync perfectly. I can maybe get it to sync right for the first minute or two, then by the end of the show the audio is all f*&ked again:|

So I guess my question is, is there a better way to do this? Or is there a program that will rip to DIVX in real time while recording or something like that (I doubt it though).

BTW, I'm using an 1.4GHz Athlon w/768MB DDR SDRAM and a Maxtor Atlas III 10k SCSI drive.

I used to have audio / video sync problems with the older Divx codec and even with Divx 5. These problems go away in Vdub when I use Divx 4.12 though.

Well, I'm using the latest Virtualdub and the latest DIVX (5.01).

I'll see if what happens with DIVX 4.12

I know it's kind of an extra PITA step, but try it in two passes. In your first pass, recompress your video with the DIVX codec and do a direct stream copy of the audio. In the second pass, direct stream copy your video and compress your audio. I *guarantee* this will get rid of your sync issue

DISCLAIMER: NOT a guarantee!

edit for bad spelling!

Well, that didn't work either

Argh! Good thing that wasn't a guarantee
When I first got into DIVX I was having MAJOR sync problems with 3.11. I tried all kinds of things (even different programs) and the two-step was the only thing that kept me from having several seconds of lag after only 20 minutes of video.
Which audio codec are you using?

I had lag even after doing the direct stream copy from the first step.

I usually use MP3 compression though at the highest bit rate.

Now I can't even duplicate my out-of-sync problem with VirtualDub (version 1.4.8) even when I disable audio interleaving and compressing audio and video at the same time :|
I did manage to do it with Sonic Foundry Video Factory. I used Fraunhofer MP3 with VDub and accidentally used the Windows version of the same with SFVF. I guess I have to experiment a little more.
I should be playing video games or sleeping! Damn you! *shakes fist*
