Hi, I have a Toshiba Satellite M110 running xp sp3. I have the Pioneer DVR-K16A DVD-RW. I was in the process of storing all my old DVDs on an external hard drive. I was ripping a documentary that I recently purchased when the DVDFab software I use became unbearable slow. I let it finish, but it wouldn't record the next DVD. I tried playing that DVD but the video was irratic and the sound kept popping. It now does this with ALL DVDs. I can still rip my CDs and have no problem with CD-ROMs but DVDs will not play without what seem to be sudden temporal shifts in the audio/video. Movies I've already ripped still play back fine. I run AVG Free anti-virus and Commodo firewall. I've scanned with Malware Bytes Anti-Malware and Spybot and have found no issues. I'm starting to become paranoid and think the anti-piracy freaks have developed their own virus. Anybody heard of this before? I tried deleting the drive in Device Manager, then isolating the old driver files so I could load fresh ones off the disk, but the drivers keep popping up from somewhere else on my drive. I searched for them and don't see copies anywhere but in the folder I isolated them to. (???) Thanks!
