medal of honor: rising sun not burning right

[neonxfirefly]

Hey all, i am new to this forum. I recently bought a mod chip and had it installed (dms 3) i bought medal of honor: rising sun, and have tried to burn it many times (i have a trashcan full of dvd's). I have used alcohol, nero, clone cd, dvd decripter, and the program that came with my burner (i forget the name) some of them have failed completely, others have allowed for the game to load up (taking about 5 minutes per level) and the cut scenes are choppy beyond belief with a new frame every few seconds. i am using memrex dvd-r on a new sony burner. i am not sure the model of the burner. most other games seem to work fine. does anyone have any suggestions? are there special settings? can someone walk me through the process?
