VirtualDub and WDM issues

[obaku]

Hi everyone,
I recently tried to capture hi8 films with a Sony ccd208e, a VTop USB capture card, and VirtualDub.
Problem is that every software and every versions of virtualdub i tried gave me an awful sound, except VirtualDub2 which has a second option that gave me a perfect sound:
- WDM support (as seen on the screenshot)
But VirtualDub has an horrible a/v sync issue which prevent me from using it.

Captures i made with STOIK Capturer or Virtual VCR are perfectly synced but it doesn't have WDM options (only the first audio line "0" of the screenshot), which result in a really bad audio.

Does anyone knows how i can fix this issue ?

Thanks in advance
