problem with back up games

well so i start having a problem with some of my games, (a lil info about my console) so i modded about a month ago with iXtreme 1.6 my samsung drive, anyways i burned about 20 games so far on Verbatim DL. And i played a lots of games.
To burn games i'm using BlueBird LG Burner, ImgBurn, Verbatim DL, also i'm checking my ISO with ABGX360 and is passing everything.
So my problem is
#rockband the Beatles (i played about an hour) then second time i put that DVD to my xBox is getting stock on black screen after showing all sponsors logos
#Dirt 2 (i played over two hours) now when i try to play is giving me a message that i need to clean the disc and stuff like that, this is happening after a few minutes of playing
#a few oter games are having same problem, i mean that message about cleaning the disc.
But i burned a lots of games and that happen only on some of them.
Is that a common problem and is there a way to avoid that?? Well if you guys need more info, let me know
