Comment:

 Closing this ticket as I don't see at the moment what else can be done.

 The framerate detection issue should be improved in 0.31 - although there
 are wider issues about livetv and initialisation of video parameters and
 codecs.

 With respect to VDPAU, I suspect 0.31 may actually be slightly more memory
 efficient when using VDPAU. There is now a clear distinction between
 OpenGL (rendering) and VDPAU (decoding). VDPAU frames are mapped directly
 into OpenGL textures for display (to be clear - 0.31 does support VDPAU
 rendering - just in a different way). In 0.30 we still had OpenGL for the
 GUI, VDPAU for rendering and OSD and VDPAU for decoding - which, despite
 code to minimise memory consumption, would inevitably lead to some
 overlap.

 What is not supported in 0.31 is using VDPAU to display video decoded with
 FFmpeg. But on the flipside, the OpenGL rendering should be better in 0.31
 as a lot of work has gone into optimising performance.
