XP MISSING MOVIE FILES FROM CD-ROM

[kermalou]

I have some movies that I downloaded from Morpheum from work on a Win 98 machine and burned them to a CD-ROM. It works fine in Win98, but at home on my XP machine I can't find the files on the CD. When I click on the properties of the cd, it says that 514mb is being used, but by what i do not know. what can I do?
