Plaback Framrate in an MPEG2 Stream

[SimonSez07]

is there a way to change the framerate info in an mpeg2 (m2v) stream, so the video plays back at a different framerate?? (for instance 23.976 instead of 25.000)

i would want to do this without re-encoding, of course, much like vdub can change the playback framerate of an avi file in direct stream copy mode.

I've never used it and right now I cannot download it, but I've read that there is a program that does what you want, MPEGed

This is (supposedly) its homepage:
http://wessweb.cjb.net/

This was the report about it at betanews:

"MPEGed allows you to easily modify MPEG file properties without re-encoding and without sacrificing quality. Such properties include resolution, framerate, and full screen aspect ratio. The most common issue with recent MPEGs downloaded from the net is that full screen playback is either 'squished' or 'stretched'. By adjusting the aspect ratio to comply with the MPEG resolution it is possible to achieve correct full screen playback. MPEGed even has an auto detect feature which will try its best to determine what aspect ratio should be used."

I think it is freeware.
