First off I am not 100 percent sure if this is the right forum for this question but this is my problem. I am using Nero 6 to make Data DVDs. I add mostly video files. When I go to burn the DVD is say that i will be burning a "MultiSession DVD" ( I am not sure what that means) I tried making a Data DVD with a bunch of different video files on it for my cousin. But when he goes to open any video file he just gets the sound. No video. Now he has Windows XP and a newer DVD Drive. I don't understand why the DVD works for me, but not for him. Does this have to deal with the "MultiSession"? I am really kind of stumped on this... Any help would be great.

I would think that it would be a codec problem. Download the k-lite codec pack (http://www.free-codecs.com/). It comes with media player classic which plays anything.
