Is there a fast way to do this? The method I am using seems long and involves

-demuxing the audio and video (bbdemux)
-audio to aiff and then add in quicktime to the video
-export to DV-NTSC (large) using QT
-export to mpeg 2 via QT

This works but is really time consuming. ffmpegX did work but the file went from 55 to 44 minutes and everything was speeded up (but in sync)! Would it have been possible to slow the file down using whatever?
