Well now im about to try a reformat on bedroom computer and try on a clean machine.
Very annoying.
Hi,
I think you might just have to accept that this is, as tourettes said, a limitaton of the Microsoft DVD Navigator. Do you have any other DVD navigators installed? Perhaps you do and this was changed during the upgrade for some reason?
Anyway, since you have not provided the steps to reproduce the problem ('seeing in My Movies' is not steps to reproduce - does it try to play the DVD when you select the folder? Do you have to navigate to the IFO file or the first VOB file?) I am not going to spend any more time on this.
Best wishes,
Mark
