Are we sure about this? I can't believe that mplayer/ffmpeg is just imagining this up out of thin air! Where should this info come from if not somewhere from within the file? Maybe someone with more experience than me can find out more?

... and i dont want to go on the dev-mailing list of mplayer with something trivial like this (oss devs can get kind of annoyed ;)

PS: ... and btw: I hate this 'visual' post writing editor. Is there a way to activate/see the usual 'code' based editing as known from other forums? ("[quote]" etc. instead of these visual blocks, which i seem to be incapable of managing ;) Or maybe i'm the only one having a hard time inserting a quote at the right point or deleting a image/quote from a block.

It's something with the pixel aspect ratio. Almost all of Ady's clips have displayed in a stretched 1.78:1 AR in QuickTime for me on my Mac, because QuickTime tends to ignore pixel AR for AVI files and display them as square pixels. My solution is to play them in VLC, which works beautifully, but since I hate VLC's interface, I re-encoded the trailer to h.264 MP4, which QuickTime displays properly, using HandBrake. That's the one I uploaded to YouTube, as well.
