DVDR GAMES DON'T WORK!!!!!!!!

Forgive me if I'm a bit pissed off but i've followed everyones tips in copying games and boot methods going and while cdr discs work fine dvdr don't load what so ever. I've even adj the laser to 600 ohms and i know the media i us is fine as i have made a dvd movie and that played fine. I've bought the AR2 v2 and now the Region X, they both boot cdr's but not dvds. I've even downloaded the AR2 v1.7 but that locks out with the AR2v2 dongle. So unless someone has any other ideas i'm stuck. Mery Xmas to you all!
