The disc are brand new, and it simply refuses to read a disc. If it reads a disc and I play it for about 5 seconds, it then says "a rare error occured please remove disc and turn off console" Why?
This could be pretty much anything (well, almost). I've heard of defect disc drives, roaches inside the console, etc.
If you know someone with the needed experience and qualifications, get them to open the console and check ist insides. If you're still under warranty, just get it replaced instead.
