"green Screen While Playing Burn Dvd?"

[JoEdaGiGGoLo]

Waddup all...
Well, last night was when I first experienced it... After watching about 30 minutes of a burn dvd, the screen had turned all green, but the sound did not lag. I thought that it might just be the dvd, but when I turned off the slim ps2, and replayed the movie to the current part where the screen had turned green, it was perfectly clear till the end. I have a dvd copying and burning software (Magic DVD Copier) and i burned 14 dvds before without no problems. Is it possibly the slim ps2 that made the first glitch or the dvd burning software? Or can it even be the dvd?

At first, i thought that it couldn't be slim ps2, because on the coverbox it said that it was able to play dvd-r and dvd+r.
Then i thought that it was the dvd, but when i replayed it on my computer and the slim ps2, it was clear.

So i'm asking all.. wheat possibly could be the problem???

thanks for any help... and for your time
