I just used MEncoder to encode correct avi movie for 8800. Ended up with a 500mb 1 hr 40 mins movie.
I was able to play fine for the first 10 minutes, then the sound went away. When I scroll the seek bar to the middle of the film, an error says it's unsupported format.
I closed it, and reopened the file, able to play the beginning, but always tells me unsupported format whenever I try to play past the beginning.

The avi file plays fine on my computer.
Other mp4 files coded by a different software worked fine.

Anyone has the same problem?
