 One of my HD-channels suffer from stutter in mythtv. The only playback
 profile defined is supposed to use the VDPAU decoder, yet mythtv decides
 the format isn't supported by VDPAU and falls back to software decoding
 anyway (and the hardware E6600 can't keep up). I first suspected it was a
 problem with VDPAU, but got clips from this channel playing with hardware
 decoding once I got a recent mplayer installed.

 The discussion with nvidia support can be found in

 It appears that mythtv asks for VDP_DECODER_PROFILE_MPEG4_PART2_ASP (which
 the hardware - GTX260 - doesn't support) while the correct format for this
 channel should be VDP_DECODER_PROFILE_H264_MAIN or
 VDP_DECODER_PROFILE_H264_HIGH.

 Other channels distributed in a similar 1080i format are handled just fine
 through vdpau.
