MPEG playback is shorter on the MAC than on PC

[Sirach]

Hello everybody, it's me again......^^lll I have so many questions about video files on the MAC. I have encounter another problem on MAC is that some video files were being "cut-off" on the MAC. Say, I have a MPEG file that's about 211MB. On my old pc, it is about 21 minutes long. When I transfered the same file to the MAC (OS 10.1.5) it only showed about the first 35 seconds of the movie during playback, and I am using quicktime 6 pro. It happens to a few of my video files (mpg, dat, etc) How can I fix this problem??

Thank you very much for your patience to answer an newbie

This might be the problem, but it's hard to tell without being there. Many stupid people believe that multiple mpeg's can be jammed together without ill effect because windows CAN play then back ok. Obviously this does not alwyas work under other OS's. Many times these mpeg's were multi-part messages posted to usenet or other unreliable distribution method.

I'm not posistive how to 'Fix" these mpegs, but it might give you something to go on.

I have that problem. I've found that VideoLan Client (VLC) will play them just fine.

Well, I have found it is due to some MPEG headers being non-compliant due to some reason or another (and giving incorrect length information).

You can actually run de-mux the MPEG using practically any demuxer out there, and then run the two chunks through mplex again. This will actually fix any problems with these files unless they get corrupted again.

Constant incomplete downloads, splicing afterwards, etc seems to lead to this.
