No solder Mod Spider Freeze?

[Cvtogate1]

I just copied Spiderman and I must say it was my first attempt to burn a DVD game. The game was burned using Prassi PrimoDVD 2.0 at 1X speed. The game seems to stutter and freeze. I was wondering does my laser need to be adjusted, could it be the media or is there a better program to copy DVD games then Prassi Primo DVD? Thanks in advance, Peter Parker.
