I downloaded some video files onto blank discs, and although my Microsoft XP laptop sometimes plays them, it sometimes mistakenly reads the discs as blank.  How do I fix this?  Also, when I download video files on my PC, they work fine.  But when I try to play the discs on my laptop, I often have a lot of trouble, such as:  1. After a movie plays for awhile, my computer will suddenly shut down.  2. When I try to play certain discs, the computer tells me that the ClassFactory can't perform the requested action (or SOMETHING to that effect).  3. The disc's video file will play, but fast-forwarding and rewinding are a nightmare.

How do I fix all of this?  Do I need special codecs or something?  Do the files play OK on my PC because that's where they were downloaded (as opposed to the problematic play of my laptop)?

Would someone PLEASE help me?What kind of video files? What format? What software are you using? What operating system? What hardware? Did it ever work right? Any details at all?Mostly AVI and DIVX.  I've tried several players, and Windows Media Player CLASSIC seems to work best.  On my PC (which never has trouble), it's the regular Windows Media Player.  I burned the discs with Record Now!, and YES, my laptop has played some of them in the past.
