I suspect this is a compatability issue with nVidia drivers 195.62
PowerDVD was working for me previously, but have had to do a clean install of Windows 7 (due to the OS completely freezing while connected to the internet - and no easy solution...)
Just re-installed Windows 7, and updated nVidia to latest drivers.
Then installed original download of PowerDVD (2029) and it wouldn't work with my graphics drivers at all...
BD_Advisor agreed the drivers wouldn't work despite the fact they are more recent than the recommended 174.53 driver...
So patched PowerDVD to 2320
And now, it at least tries to play... It plays a very slow slide show of dark screens, one slightly tinted red, one blue, and one green, followed by a very short burst of noise, - and repeat. The time counter processes VERY slowly, as though it is playing at something like one quarter of a frame a second !
My sound drivers et al. are the same versions as on my previous Windows install - I'm pretty certain only the graphics drivers are more recent than I used previously...
Shame that the requirements of nVidia "v174.53 or later" is NOT necessarily true, and that 195.62 doesn't seem to work.
But then 195.62 is a Beta driver, (afaik), so perhaps we don't have reason to complain... And yet, I can't help feeling that Graphics driver versions are about the bleeding edge of 3D gaming, and NOT video playback.
So, all in all, I think Cyberlink are pretty rubbish, and PowerDVD yet again shows how damn sensitive it is to what should be a relatively small change.
