There's an option in VirtualDub somewhere (in capture mode, but I don't remember where) to synchronize video and audio. I can look it up this evening... This option will lead to a few dropped frames due to the way synchronization is handled.
There's another version called VirtualDub_synch which is told to synchronize using an advanced method without dropping frames. But that one is not available with a timer like VirtualDub_VCR AFAIK.
