Many thanks for the clip.

I'm not sure if anything exists at present but it shouldn't be too
hard to get the basics working.

As I see it there are 3 main problem areas, from a MythTV perspective:-

- for those who have 3D televisions that can play back the 3D
broadcast material they have, some MythTV functionality won't work
properly. As AntiCat has seen, the OSD needs to be rendered
differently and it is likely that various zooming and scaling
operations will confuse the tv's 3D processing.

- if you just want to play it back using your existing, standard
monitor and some red/cyan glasses, then a post processing filter is
required to take the two images and blend them together. This is not
technically difficult but the complexity lies in the number of
different 3D formats (side by side, top/bottom, interlaced, full frame
based - and those are the easy ones) and the different rendering
methods (writing a post process VDPAU filter is currently not possible
with MythTV - should be fixed soon though)

- I think, though I'm not sure, that some of the newer 3D hardware
(nvidia glasses etc) relies on proprietary technology that isn't yet
available on Linux.
