I dont know if anyone is still paying attention to this thread or not, but they gave me a new link for download to try. So I downloaded it and installed everything. After doing this I did notice something. After the install it would start up imediately. I could close it and restart it over and over again and it would still open immediately. BUT, after I left it for awhile and tried to come back and use Power DVD it would again take about 2 minutes before it would open. From that point I could close it and start it again. It would open immediately.
So to me it seems like something happens after you close PowerDVD and dont use it for awhile.
