For all of those who own the Philips 3300H who couldn`t get the multi region hack to work then try the following trust me it does work this way.
Turn dvd recorder on.
Put into DVD mode.
Leave disc tray closed (very important bit)
Press play 159064135124255 play (fast)
Turn dvd recorder off.
Turn dvd recorder back on.
Hey presto it is now multi region, if it doesn`t work first time try it again typing in the numbers faster and it will work.
Let me know if any of you have had any success doing the hack this way.
Hope it helps.
