Playback of 3D with Power DVD ultra FramePacking.

[Datus]

I have a cinema setup with active shutter glasses using 1.4a hdmi.
I use power dvd ultra 10.

with blu-ray 3D it works fine but with mkv rip of a 3D film PDVD10 treats it as a 2D film and trys to convert it to 3D which is obviously poor.

I am guessing there is some trick to this I am missing or perhaps I need PDVD12 or a different player.
I prefer to keep to PDVD as the sound processing with that program I have found is amazing.

can anyone help.

If I have to use .iso for the few 3D films I have then be it as its not a big issue but I hate having something beat me that I know is doable.

Update: I am refering to full frame packing, I think mkv can do side by side but I would like full frame packing

i have the same issues, i've not managed to get any 3D MKVs working in 3d unfortunately, they all play in 2D
