error converting TOD files
 

I just converted a couple TOD files from JVC HD7 camera for the first time, and the resulting avi are missing a significant chunk of the footage.
The first was 3:10 and after converting 1:53
the second was 1:03 and after converting 0:40

Any ideas of what went wrong?
Watching the avi, video is missing throughout the clip, but sound does stay in sync with the video that is there.
