no solder mod (plays dvdr) should i get dvd burner?

[GmRunner]

okay guys here is the deal. I got the no solder pnp mod from lik sang.com. it says it can play cdr and dvdr but then i heard that the no solder cannot play dvdr over 650. so does that mean any dvd i would play i would have to rip to under 650? is it worth while for me to get a dvd burner? like say I get a dvd burner can I simply burn (backup) a dvd game i have liek resident evil code veronica to a dvdr and it will work? would i need to do that load game shark switch to an orginal large dvd then go to without codes and eject and put in the dvdr backup? i am new to all this please explian guys. because i dont see what good playing dvdr is if it cant play over 650 hehe if thats the case how is it any better than cdr?
