DVD burner problem. Any Help?

I can burn files onto a dvd with my dvd burner on my laptop, but then the dvdrom/rw on the laptop is not able to read any of the files on the burned dvd, even though my PC and my buddy's dvdroms/rw can read the files. I have daemon player installed, and thought that might be causing problems, but when I uninstalled it I was still getting the same problem of the laptop dvdrom/rw not being able to read any dvds, even though it can succesfully burn dvds. Any help would be greatly appreciated. Thanks.
