I got it working using NVIDIA 3D Vision Video Player if anybody is interested.

I got it working by using and Cyberlink's Video Codec and Arc Soft Audio Decoder.

Open up the NVIDIA 3D Vision Video Player, choose File>>Settings>>Decoder>>DVD Decoder.

For Video Decoder choose - Cyberlink Video/SP Decoder PDVD 10 UPnP

For Audio Decoder choose - Arc Soft Audio Decoder. (or what ever Decoder you have on your system. (Trial and Error)

Doesn't solve the PowerDVD 10 Ultra Mark II issue with 3D playback (but at least it works)

Try this if you want. There are one or two more steps that might be necessary - see how you go.

By the way while trial and error please note you have to maximize the DVD window to Full Screen for the 3D feature to take it's effect.

Regarding the error of playing 2D DVD to 3D

I just tried the solution of Cinema Mode in Power DVDs (as mentioned above) and it plays - but it only plays in 2D.

Does anybody else have this problem?
