Hi, I have a PHILIPS DVDR1628P1 DVDR/RW drive and i'm having some problems with it. Everytime I use the drive to install games/play cds/Rip cds/ back up dvds etc, the whole computer begins to 'stutter' the mouse becomse a little stuttery and any audio played comes out stuttered too. Also it takes ages to back up dvds, like 4hours. I've updated the firmware to the most recent of 2.4 so has anyone got any ideas how to help me? Many thanks, Jamflan
