And at least according to Wikipedia:
http://en.wikipedia.org/wiki/H.264/MPEG-4_AVC#Levels
AVC HP@L5.1 apparently would allow for much higher resolutions than 1920x1080, wouldn't it?
Also, in the LAV Filters thread apparently the following was posted:

NVIDIA (via CUVID) only supports it with VP5 (VDPAU Feature Set D). AMD claims to support it with the 7xxx series, but in my tests, it just failed miserably.

And apparently when playing back 3840x2160 video here for example with a GT 520, hardware acceleration apparently is only shown as "active" in the LAV Video Configuration panel when it is set to LAV CUVID or LAV DXVA2 (copy-back).
But when setting it to LAV DXVA2 (native) or when using internal MPC-HC Video Decoder it apparently is falling back to software decoding.
Why are resolutions beyond 1920x1080 blocked with LAV DXVA2 (native) and internal MPC-HC Video Decoder (which is DXVA2 native as well, isn't it?)?
