Hi Coops,
The problem you are having is because your not doing the hack correctly,
Remove the disc from the player and close the draw, the player will now display `NO DISC`. Now you can press play 2,7,4 and enter the code for the particular region.
If you wish to have full multi region playback you will need to get the player reprogramed or chiped.
I can reprogram the player for you cheaply.
You can contact me @ ewc-aelr[at].moc.12klat
Regards,
Rick.
