after a lot of troubles with my DP 558 I finally decided to send it back to KISS.
(my DP 558 has troubles playing back nearly all of my DVD's - sometimes I have to eject DVD's 10 times before they play -if at all)
Currently, The device is Region free (made with a CD mentioned by Hi Jack here in the forum)
How can I revert it back to RPC2 before returning it ?
