I am using Win 7 OS and PowerDirector 10. I have been using this program for quite some time with no difficulties, except slow rendering. Today, a new wrinkle. Same computer, trying to import .mpg files (mpeg 2 format, from the same sour that I have been importing from for several months. System just sits there. If I try to import a 30 second spot, it takes about 2 minutes. The "importing scenes" sits at 0% and does not move. Anyone else having this problem?
