Hello. I recently downloaded Narutimate Accel, Bleach Blade Battlers, and Kenshin, which played flawlessly and with no problems. On the other hand, while downloading and burning Guilty Gear Accent Core as well as NBA Live 2007, whenever putting it in, it makes loud grinding sounds like the DVD is hitting the laser. On all games, I am using Verbatim DVD+R's. Does it make a difference if I'm using DVD-R's? Also any idea why the grinding sound is only on some games? I tried adjusting the laser also, but with no success on those two games only. Thanks a lot!
