Hi, I have a Samsung SH-S22xSATA DVDRW and a DVD-ROM 16X installed in my PC which is running Vista 7 (newly installed). The PC is 18 months old. Until today both DVD drives worked perfectly but suddenly neither will play a disc. The "tell tail" on each drive flashes when I insert a disc and close the drawer but notheing else happens. When I eject the disc after it has been in the drive for a few minutes it is warm. This applies to purchased and to home recorded films. I haven't installed any new software other than Windows 7, or hardware since the last time the drives worked. Any clues as to what may be causing the problem and suggested remedies would be appreciated.
