Still freezing when i play music and try to quit with(O),but no Black Screen for now!
Well I wouldn't recommend that you try to use the Media Server features in JB mode, but you can load up Deanrr's Multiman and play music/videos from it if you like. What are you trying to exit when it freezes? Good to hear that my advice was at least partially right.
But now when i turn ON PS3 and press eject to JB. Show me a message "The hard disk's database will be rebuilt" and i press OK. Something work about 3 sec. Then i turn OFF. JB again and works normaly!?!
