Philips DVDR75 Recorder Multi Region

If I copy a movie DVD on my PC it will not playback on the DVDR75 but will playback on the PC and other home players. The best I have so far achieved is a disc that will play the info chapter, but no more. Is there any software that will overcome this problem that can be recommended?
I have downloaded (and thought about installing) the firmware upgrade from Philips but haven’t a clue how to install it and wether or not it will make any difference. Any advice will be appreciated.
