This just started last night while i was backing up a few of my DVDs. The first two went fine but when encoding the third one DVDshrink lost my dvd-rom, literally. My dvd-rom drive was not found in explorer or device manager. I played around with DMA and PIO mode and got it back in explorer but both dvdshrink and device manager can not see it. For system specs my OS is winXP running on 1.8ghz with around 1.5GB of ram. Like I said, the first two went fine, but on the third one everything went loopy. "I am a lost little boy, Can somebody help me?"
