Where did you get the original length from?  Is "133799" the number of
video frames in the file?  Does the audio track start at the same time
as the video track?  Is it the same length as the video track?  At least
on a DVD the asnwer to the the last 2 question is not guaranteed to be
"yes".

Are you claiming you have corrected for both of those by trimming
samples off in some program?
