VideoStudio :: Import From Digital Media In Pro X5

I have recently upgraded to VS Pro X5 from VS Pro X2, and have a question about the import from digital media feature. I've ripped my DVD folder to my HD and select Import from digital media. The title and chapter thumbnails appear, but it takes a while for the graphics to appear. Also, when I try to play an associated thumbnail to determine exactly what I want to import, VS Pro X5 enters a non responding state for some time, depending on the size of the video. It does eventually continue and plays the title or chapter. When I select the title or chapter for importing, it does in fact import, it's just the delay in playing the clip that I'm questioning. But when I run the same process on the same computer in VS Po X2, the process is almost instantaneous. Since both programs are still installed, I realize that I cam simply use VS Pro X2 whenever I need to use import from digital media. It's just odd that the earlier version of the program would perform this function better than the more recent version.
