Hi Michael,
The reason I didn't post the information is that it is totally irrelevant.
The fact of the matter is that the menus are in 3D, but the movies are not - whilst up until 2 months ago, it all worked fine.
I have in the last 2 months installed the PowerDVD10 patch & installed ArcSoft TMT5 - looking at the latest Nvidia drivers released 8th Nov 2010, I will have installed these too.
3D works fine with games, and with TMT5, and strangely with the 'menus' in PowerDVD.
My initial thoughts, given that the majority of other people will have the latest NVidia & Cyberlink drivers/patches, are that perhaps the TMT5 has stolen some type of file protocol from PowerDVD ?
I'm basing this on the fact that the menus are 3D in PowerDVD, so it is processing 3D for this file type (whateve file type the still image menues are) but the actual movie footage isn't, so therefore PowerDVD is not processing these files properly.
As you have asked, the display is an Acer H5360 projector fed from a GTX480 via DVI-HDMI, and set at 720p @ 120hz.
Other than the above mentioned updates/installation, nothing has been changed on my PC, and no other software installed (other than obvious Window 7 64 updates & Norton 360 updates).
I can't see the latest NVidia driver being the issue, as there would be numerous people complaining about this issue, and similarly if it was the latest PowerDVD10Ultra Mk2 update - 2325)
I have unassociated all file association within TMT5, and made PowerDVD the default player for Blu-Ray, which hasn't helped (and in all fairness I didn't think would).
It is my understanding that the regedit produces an hierachy of codec's, and although I assume each programme uses its own/preferred, could it be that the later installed TMT5 software has put a codec at the top of the list, and this is in someway stopping PowerDVD from using it's????
Any help is appreciated - and as previously stated, I do not intent to uninstall TMT5 due to an ongoing issue with PowerDVD on a minor amount of movies which makes them irriating to watch, and thus needing TMT5 as a back-up piece of software.
Regards,
Dean
