What DVD player software are you using?
Many of those RIPPERS have bad side effect such as destroying installed DVD software.
To test if your machine can play Video DVDs use a factory made Video DVD and run VLC PLAYER (use google to find it.)
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!
