I Have backed up most of my games with no problems, but some I did just recently are totally useless. they are no were near as good as the originals, like how it sounds which just isn't the same. The game is Shellshock Nam '67, and the sound must be hidden or encoded on the DVD as tracks?. I can tell there is a huge difference with the sound of the original on my surround sound compared to the backup which sounds no were near as good!. Also it's very annoying, the rest of my backup games play fine but there this one causes the laser-eye on my PS2 to go back and forth very stupidly and the game takes longer to load than it does with the original. I'm concerned could that disc reading behaviour end up damaging my PS2?, cause it's got me f%*#ing damn worried. What about the DVD media quality does it matter which one i use, is it important?. Because I use TDK 4.7gb DVD+R's, are they allright?. Thanks.
