In attempt to figure out that full HD double frame 3D video stuff I re-encoded the files in 24 and 30 FPS. Posted links in the end.
3840x1080 in ffdshow and TMT3 give BSOD regardless of frame rate.
1920x2160 plays smoothly in WMP (ffdshow) and TMT3 but not in MPC-HC with ffdshow so I can't provide good MPC-HC Ctrl-J screenshot. Chart is bad in MPC-HC and video stutters. 60 or 30 fps doesn't matter.
Can't think of more proof other than posting video on youtube (below)
None of these files play on GT240 in ffdshow (stops immediately) or MPC-HC internal codecs (black screen).
VLC Player played 3840x1080 files.
30% CPU usage on GT240 and quad core Q9550 but it horribly stutters, unwatchable.
50% CPU usage on HD6850 and dual core E8400 and it looked OK, no terrible stutter. I think, it's watchable (video below).
I can't explain bad results on GT240 in VLC Player as I don't think version 1.0.5 uses DXVA so theoretically video card should not matter. In any case, overall, AMD UVD3 gives me better results than NVidia VP4.
And PowerDVD 10 still can't play double frame files. It used to, not sure what I broke. PowerDVD plays normal 1080p content just fine. And MPC-HC works perfect with normal 1080p files with DXVA both with ffdshow and internal codecs.

: Relevance of all this testing to 3D
Neither StereoMovie Player nor Stereoscopic Player 1.6.6 could play these files.
I made PowerDVD 10 working on these files by installing latest update, 2429 (just erasing all old settings would do the job, I think).
PowerDVD plays them and it sort of shows 3D in anaglyph mode on my 2D display (can't see depth in red-cyan glasses but I guess videos were not meant to be real 3D).
The thing is with PowerDVD CPU usage is 100% on HD6850 and video stutters really bad (video hardware acceleration is checked and it works fine on normal 1080p files).
PowerDVD 10 plays 3D blu-rays in anaglyph 3D mode smoothly with 2-10% CPU usage. There are issues with double frame video only.
Maybe TMT5 will do better, can't tell.
