Sony DVP-SR700H region-free hack
This hack requires the use of a ONE FOR ALL remote control.
See link below but note the following differences:
When you set up the ONE FOR ALL remote with the code 0 5 3 3 you need to first press the DVD button then hold down the MAGIC button until it blinks twice fast (it will blink once first then twice fast after that) you then enter the code 0 5 3 3 and then press the MAGIC button again to lock it in. The use of the magic button is note mentioned in these instructions for locking in the code....
ALSO when you use the 1 2 3 4 5 button presses you DO NOT get SUCCESS on the screen you instead have the unit show 0h then the DVD tray starts to open and close partly and continuously. You now enter 1 2 3 4 5 again and it stops and says OFF then turns back on again. (the instructions say it turns it off) you have to turn the unit off with the button on the machine. Pull the plug out for 5 seconds then plug it back in and turn it on and you are good to go!!!

Thanks to the person who typed up these full instructions originally. With this tweak to then you will be good to go.
I have three of the same machine and it worked a treat on all three :)
