I use Recordnow max all the time for both movies and PS 2 games.
First you will need DVD Decrypter or similar ripping program, then DVD2One, before burning with Recordnow Max.

I would follow Bighap's advice and persist with the DVDXcopy programs as they are reliable and simple. Or alternatively download DVDShrink. It is also a relatively simple program to use.
Good luck
