You assume correctly. The sound is out of sync as you are listening to the 
sound directly from the card but you should be listening it from the file 
mythtv creates on the hard disk (normally 2-5 seconds behind).

I don't know anything about setting up framegrabber cards and I'd recommend 
getting a PVR150 card instead.

At a guess I'd imagine you need to unmute something on your mixer (line-in?) 
and mute something else.
