I've only ever installed one CVS (last week, after some very positive reports, I wanted to see if my tearing issue had magically disappeared).
When I copied the old directory back in, I started getting .NET errors. I had to re-register directshowhelper.dll and then everythng was OK, but now I feel like I have a "damaged" MP install...! Not to worry, I will be doing a "re-image" soon as part of further testing....
