Took the words right out of my mouth.

This definitley looks like a laser issue.

Unfortunately with the version 4 u do get problems on account of the laser being pretty poor and there aint a great deal u can do about it.

My m8 had the same problem and we recalibrated his laser using an oscilloscope to best it possibly could be and it still froze sometimes on GTA Vice City and wouldnt even get to the game on The Getaway and that was on ritek G03 DVD-r.

We then dropped in a new laser and calibrated that perfectly and still got the same problem. In the end we sold it and got him a second hand version 5 which plays all dvd-r perfectly.

It still worth giving the laser a clean. If that don't work then I'd seriously consider upgrading to a version 5,7 or 8.

Good Luck
