First of all, the description you provided is more misleading in understanding the real problem. Whatever, the problem is you when double click the movie file on CD, it doesnt play, informing what while its of mpeg or avi the data inside is text. Then simply, you can right click, choose play in Media player. This would play the file. Otherwise, you can also do, OPen the Totem, Open File->Browse and select the media file. This problem is not known why, but nautilus checks the initial data combination to certain that file extension is right, and then it get messed up with little diference, which are really different encoders on windows do write diff data in initial encoder segment values.
Anyway, that was a problem in my computer in Edgy. In feisty, its not happening all the time, though some time it gives similiar msg. If it doesnt solve this way, you need to check if your cdrom is properly working, my last COMBO(which i broke punching, for not behaving properly), was having weired kind of act. It was able to sometime copy data, othertime it just give IO errors. Movies not playing anyway and songs too.
