Problem Playing Back HD Discs

[kronik8]

Sigh. Read through this thread some and got lost, so I figured I'd just ask my question.

Until yesterday, my Blu-Ray/HD-DVDs were playing fine in my LG dual-format. I changed to an Omaura case, which could not accomodate my 8800 Ultra so I purchased an 8800GT. After installing the 8800GT, none of my high-definition discs work. I'm running 169.25 ForceWare drivers; not sure what version of PDVD7 Ultra I have. They all play in a stuttering / slow-motion fashion and their audio does not work. I've tried:

Inside Man
I Am Legend
The Departed

Any ideas? Tried installing 175.16, the issue persists.

I just installed that drive yesterday and had a similar problem. I had put in a 8600gt and was getting a lot of choppy playback. I fixed by installing the newest Nvidia driver and checking the Hardware acceleration box in Power dvd. Look at your cpu usage when playing back an hd video. If it is at 100% that is probably the problem.

Tried it with and without - same issue; CPU usage is at about 50% during playback.

I'd get the latest PowerDVD 7 Ultra and/or PowerDVD 8, then see what happens. Also you could use http://www.guru3d.com/index.php?page=driversweeper and clean out the current drivers you have installed, and then get the latest non-beta WHQL drivers for your card from nvidia's site. I'd also install the latest directx. http://www.microsoft.com/downloads/...9A-5B72-447D-84F9-EE6407ED1A91&displaylang=en

It really sounds like it isnt using the GPU at all and is in fact using the cpu, can you double check your options?. It sounds like cyberlinks single threaded filters using up all of 1 core on your system to try and playback the movie (thats if it is dual/quad core).

I cant remember exactly but was purevideo H264 or something not working/done by the stream processors on the first set of 8800GT's, maybe it something like that, although i could be 100% wrong.

Hardware acceleration is turned on - is there a way to check past that?

I am losing my freaking mind..

So -
Uninstalled/re-installed all codec packs - no change.
Uninstalled/used DriverCleaner.NET/reinstalled (all in safe mode) the 175.16 drivers - no change.
Uninstalled/reinstalled PowerDVD 7 Ultra - no change.
Installed PowerDVD 8 Ultra - no change.

Again, the CPU usage is the same with the hardware acceleration flag on or off - constant stutters.. like a 2 frames per second. I contacted EVGA support and they're not telling me to do anything that I haven't tried.

Anyone have ANY ideas?
