.wmv audio and .mov video out of sync
There are several possibilities here.  It could be that one device or both dropped frames and thus ended up out of sync, it could be a difference in frame rate or it could simply be that one or both devices have inaccurate internal clocks for recording.  Your best bet is to identify a point at the beginning and at the end of each video that should be the same.  Figure out the offset and then do a speed adjustment to one of the clips to make it line up with the other.

After you do this, the beginning and end should both match up, but you still want to make sure to watch the entire video closely to make sure it stays lined up the entire way through.  If the loss of sync was due to dropped frames rather than a difference in clock speed, the rate adjustment will not fix the problem and you'll see sync issues emerge somewhere in the middle of your video.

If it is due to loss of frames, there isn't a lot you can easily do to recover from the problem because you are missing the information that should be in those frames.  If it is an internal clock rate issue or an FPS issue, then there is a decent chance that the rate adjustment should fix it for you.
