Keith,
I haven't had much luck with the '5105 patch at all! Power DVD 7.3 Ultra insisted I download the patch or I may not be able to play any HD discs at all.
Since I've installed '5105, my Power DVD 7 just won't start! All I get now is an error message and then the program aborts! This isn't the first time this has happened with Cyberlink patches and upgrades and to be honest I'm getting a little tired of it. I thought patches and upgrades were supposed to enhance the enjoyment of the product not stop it from working!
It's funny, I was thinking to myself just the other day how well I had done to finally get my HTPC running reliably and stably then this happens!
InterVideo has released it's WinDVD 9 plus Blu and I'm going to buy that and give that a try. My Power DVD can go on e-Bay I think.
Good luck mate.
Elst.
