I'm glad everyone is trying to find a solution. However, 7.3 works perfectly for me and I have no issues, even with a bunch of programs loaded to my PC (including BeyondTV 4).
I thought Power DVD Ultra Version 9 would be a huge step up. It was an extreme disappointment as I could never get past the menu screen on a Blu-Ray DVD (always crashed). Tried 5 separate installations, including deleting version 7.3 (probably running out of activations too).
I already submitted a ticket to tech support and indicated if this problem is not fixed, I want my money back.
I wish I had read this forum first before buying. Any suggestions for alternative Blue Ray software players? Thanks!
