1. It won't read DVDs, Blu-ray and and PS3 games are fine but any time I put in a DVD the screen goes black and the system locks up.
2. If I turn the system off with a game disk in it then it won't detect the disk when it it switched back on, the disk has to be ejected and inserted again.
Since this has started happening I have reset the PS3, installed the latest system software and reset it again but no luck.
