Thank you for your reply...
I would like to make some contribution to mplayer development, and I think
fixing the problem of dts decoding might be a good chance to get familiar
with the mechanism of mplayer codes. But I can't determine where the problem
really lies quickly because I am a new hand..
Maybe I should goto the mailist of ffmpeg developers?
