So I did this: cat video.m2v | head -c -2 > video2.m2v cat video.m2v | head -c -2 >> video2.m2v cat video.m2v >> video2.m2v There seems to be more to it because now I get a: ++ WARN: [mplex] Data follows end of last recogniseable MPEG audio frame - bad stream?

They do. > Obviously, for a multiplexed program stream: cat - forget it ;-) I already thought that much. -- Lehmeier Michael <[EMAIL PROTECTED]> ------------------------------------------------------- The SF.Net email is sponsored by EclipseCon 2004 Premiere Conference on Open Tools Development and Integration See the breadth of Eclipse activity.
