hey. yesterday i was playing tiger woods when the controller low battery message flashed up on screen. i hooked it up to the usb slot and then the game froze. anyway, got back to the ps desktop and tried to load up the game again but no joy. tried some different games. no good. and some dvds. still no good. basically the player won't read any discs. i tried reformatting the machine but this didnt solve the problem. any advice? my ps3 is less than 1 month old.
