I have purchased Power DVD 9 Ultra and installed it on my computer which runs Vista Ultimate (x64). Earlier, on the same setup I have Power DVD 8 Ultra and my blu-ray discs used to work.
Now, when I play a movie, PowerDVD says "Loading Blu-ray Disc..." which completes and a playback screen blinks for less than a second and the dis-appears. This happened with all my discs not just one.
I have formated and reinstalled my computer with the latest updated OS, Software and Drivers.
There is NO error. But it still does not work.
