My friend used his Hitachi Mini-DVD cam to film some clips and then exported to his computer and put them on a CD for me to edit. They are .mpg files in MPEG2 format. However, when i open them from the CD, they play, but i get a box saying Windows media player / Explorer has encountered an error and needs to close. This happens in every video player, and also Windows Movie Maker and Adobe Premiere. I'm stumped as to what the problem is, anyone have any ideas? We have tried numerous CDs so i dont think the CD data is becoming corrupt.

Thanks for any help
