did you buy it abroad different region if so that might help! seen that written in( av forum)
DVD1 must be powered off (mains lead out), with no disk, and connected to a TV.
Hold down the << and >> keys and restore power. Release the keys.
The display will show "r02" or similar, indicating the current region setting for the player. Use the << or >> key to change the 02 to the region you want. Then press the play button. After a few seconds the TV screen will go blue and this shows that your DVD1 is now re-coded.
However: There appears to be no "multi-region" setting, although the first time I tried to modify my DVD1 the display showed "r--" but after that I could never get back to it! Maybe if I'd been smart enough to hit play straight away it may have made my DVD1 multi-region. Who knows?
Also, I believe that one can only change the region setting for the DVD1 twenty times before it does something nasty, like stick [permanently on the last region setting you chose.
