How about this. Try another PC.

For no apparent reason, the audio and video plays on my PC at 50% the original speed.
There seems to be no issue with my camcorder - the Sony DCR-HC14E plays the video without problems on the camera.
All I can think of is that the firewire card is capturing too slow, but there isn't anything I can do with it!
Help!
