I guess that's another timestamping bug in ffmpeg.

As far as I can tell, the bug affects only decoding timestamps (DTS). Ffmpeg calculates them from the PTS values, but in a rather crude way. The dvbcut muxer is a little more clever and does The Right Thing (tm). -- Michael "Tired" Riepe <[EMAIL PROTECTED]> X-Tired: Each morning I get up I die a little ------------------------------------------------------------------------- Take Surveys.
