AIR Radeon has started to audio drift while capturing

[sonoma]

I haven't changed any hardware, but am now getting audio drift while capturing to avi(huffy). I don't get any dropped frames, (which would probably help, since the audio gains on the video). It never used to do this. I am now using the Santa Cruz 4161 drivers, the ATI Catalyst 2.5 drivers, and MMC 7.7. I don't see a setting for keeping audio/video in sync. Turtle Beach said it was a clock issue between the SC and AIW, but it used to work perfectly. Anybody have any words of wisdom, before I reformat, and reinstall from scratch.

Try capturing with virtualdub, if it is a clock difference between the sound card and capture card that is causing the problem, virtualdub will drop the odd frame to maintain AV sync.

Another alternative is to capture MPEG 15Mbps VBR.

Well, I capture 480 x 480 avi, edit commercials, then Tmpgenc CBR fit to 800 MB.
I think that starting with MPEG, editing, and re-encoding would give me worse results.
I like MMC, it's easy to use and pretty automatic, but I'll give VD a try, but I'll need a VFW wrapper won't I?

Depends on your operating system, the vfwwdm wrapper is built into xp, not sure about 2k

For anybody that cares, reinstalling w2k, catalyst 2.5, mmc 7.7, fixed the problem. ACPI put nic, sound, raid, video, etc on IRQ 11, and it all seems to work fine.
