There are plan to add Blue-Ray support in to MP in feature, so PowerDVD will be no longer needed.
If you want to use PDVD + SAF, you can remove registry entry "hkLocalMachine\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{2BF2E31F-B8BB-40A7-B650-98D28E0F7D47}\" ident "DisplayVersion".
PDVD will be no longer detected by SAF.
I think native BD support will need quite some time especially with menus and all that stuff - if this will be supported at all. So PowerDVD 8 is mandatory for many BD users for the time being.
I have installed SAF 3.42 - it also doesnt want to install when AC3Filter is present which I have installed for good reasons. I really like your work at SAF and appreciate it, but you shouldn't patronize the users by saying what they are allowed to install. A warning (no support etc.) would be enough.
Cheers!
