some disc no matter what enviroment system is in are completely unreadable. system says no disc in drive. namely tv shows. it starts reading the drive then says no disc in drive. any ideas about this would be appreciated. thanks in advace

got to bolt mike out

If the disc doesn't appear, then it's a read problem, which means the drive can't see the disc, and has nothing to do with the OS. That means either the disc needs to be cleaned, or the drive itself is failing.
