A/V Synch Errors with Nerovision Capture

Has anyone else been having progressive A/V synch problems with ATI capture card? Nerovision says 0 frames dropped. My other capture utilities don’t have any problems at 720x486 mpeg2. Synch problems using either AC3 or LPCM.

Nero support could only say there was something wrong with the mpeg file (of course) and told me to use an mpeg repair program.

I’d get a new capture card or sound card if that was the problem but I don’t think it is since my other capture software work perfectly. Everything else in Nero works perfectly except for this. I’d really like to use Nero for capturing, especially for DVD+VR but I can’t seem to get past this one thing.

Any input is welcome.
