Choppy video after Spybot S&D install

[WRCguy]

Ok, so it probably doesn't help that I'm running Windows 98, but I've been happily watching videos using VLC for over a year now. However, ever since I installed Spybot S&D I've had coppy video issues. I figured it must be the Spybot and so I uninstalled it. In hindsight, I should have reversed the changes made by Spybot FIRST, but instead I accepted them thinking that they couldn't have effected my system files. Still choppy video. I've since done a diagnostic of my DirectX - everything clears. I've also tried uninstal and re-installing VLC - no change. Any suggestions?

Thanks!

Any suggestions here? Is there someway to make sure that my drivers are ok? Is it possible that Spybot has left me with some registry issues?

Thanks!
