Page 1 of Moulin Rouge doesn`t like Goodmans

Bought R1 Moulin Rouge but it won`t work on Goodmans GDVD 100. Early scenes get distorted after a couple of secs, then whole thing freezes up.
Probably not the best player but has worked well until now. I know the hack OPEN, SETUP, STEP, PREV, NEXT. Would changing the version help? any one know what they mean?
DVD works on the PC so it`s not damaged.
Help!!!
