48 fps and 50 fps video decoding is stutter on UVD, even 720p. UVD on Radeon
6310 with fglrx driver as able to decode up to 1080p 50 fps video with zero
dropper frames so hardware is capable of decoding such framerate.
There is 48 fps sample
<a href="http://dl.dropbox.com/u/11564551/Inception_trailer_48fps.mkv">http://dl.dropbox.com/u/11564551/Inception_trailer_48fps.mkv</a> but I want to
notice - many camcorders record 1080p50 or even 1080p60 video this days, so
this issue not just about trailers that upscaled from 24 to 48 fps.
