Philips DVD 622 region-free hack
Here are the steps. I added some detail:
1. Connect DVD player to your TV, turn both on, remove any disc that might be in the player and close door.
2. Press and hold Stop button on the remote (not the one on the player) until door reopens
3. With just the default background displayed on TV (blueish image of disc center with PHILIPS on disc - do NOT press the System Menu button), press 2 8 1 2 on remote. In a moment, the Region menu will be displayed.
4. Press OK on remote to cycle through region codes until region changes to 9
5. Power off DVD player (with Region menu still displayed showing 9)
6. Wait 2 minutes (according to some others' directions; I'm not sure the 2 minutes is necessary) then turn player back on.
Thanks to Jeff Cadow for supplying this hack.
