just to explain what Randy is suggesting...  you're likely getting the
"live" audio, which will be early compared to the "buffered" video, so
you want to make sure you're getting the audio that is also buffered
so that it syncs.

usually, you do this by taking the steps Randy suggests
(just a little more detail):
- set LineIn as your recording source (sometimes "Capture")
- mute the LineIn (so you don't hear the "live" audio)
- check that your audio device is setup as the "output"
  device in Myth's Playback setup
