I own three region 1 DVDs I can no longer watch :(

I`ve just hunted round the web, and all I could find was this suggestion, so it has to be worth a try. No one responded to say if it worked where I found it, so perhaps you could let us know.

11. Player is now region-free.

1. Remove disc from tray. 
2. Switch off player and unplug from mains. 
3. Wait 30 seconds, then reconnect mains. 
4. Turn on player with remote. Wait for player to finish loading and display `no disc`. 
5. Press enter on remote. (There will be no on-screen response.) 
6. Press 8, 4, 2, 6, 9 on the remote. (There will be no on-screen response.) 
7. Press enter on the remote. Player will automatically shut off. 
8. Turn player on. 
9. turn off. 
10. Turn player on again. 

It should now be region free...
