has anyone out there been having trouble playing THE ULTIMATE MUMMY in there panny a160. the only way for the player to accept any of the discs is to eject/close cd tray several times,before the player actually accepts the discs. also having trouble with another disc THE POSTMAN(the wifes disc). can anyone out there make any suggestions. is there a firmware upgrade or is the player on its last legs. help would be appreciated..
