I have modded a couple of v12 with a ripper 3.1 -> no problem
No I did 2 v9's and they play games ok. Problem is that when I insert a dvdr movie it looks like it's about to start the movie, but then the screen stays black. when I insert a original movie, it boots ok. When I disable the modchip dvdr movies works.
Doesn't seem to me this could have to with a incorrect install.
