Problem Mpeg 4 movie skips to end when i fast forward or stops halfway through movie?

Everytime i try to fast forward on these types of movies it skips to the end? I have looked at the manual and there shouldnt be a problem with the codec?

What program did you use to encode the file?  It sounds like bad/missing headers within the file.

I don’t know the decode limitations of the Amlogic chip… I know the other WDTV devices that use the Sigma chips have further limitations as to what profiles are supported within each “supported” codec.
