I am having problems with my Toshiba DVD-ROM SD-M1402. For some reason, it's always worked in the past perfectly fine. But recently, it refuses to read regular CDS/burned CDS. It just spins/spins/can't read. However, if I put in a DVD, it spins for a little, then reads the DVD and I can watch a movie. Do you guys have any idea what's wrong with it? Running WinXP. Please help
