I'm currently experiencing problems when playing videos on my AMD fusion e-350
with HD6310 graphics(r600) with OpenELEC 4 beta2, which uses Mesa 10.1 and the
latest Linux 3.13 kernel. This is with the system connected through HDMI to my
television.
Either the video is being decoded too slow, which causes skipped frames, or it
is decoding too fast, which causes missed frames.

23.976fps becomes 23.92/23.95 and sometimes goes to 22.93fps
25fps becomes 25.02 or 25.05fps
29.97 interlaced decodes with around 58fps instead of 59.94fps.

It is if like the clock that is used for decoding is all over the place (PLL
issue?)

I confirmed with the old OpenELEC 3, which uses AMD's fglrx, and everything is
playing perfectly and the fps is spot on, as in. 23.98fps, 25fps and 59.94fps.

I also tried disabling the new VDPAU hardware acceleration and VDPAU mixer, but
with no effect.
All tests were done with the television frame rate being matched to the
content, so for example in the case of 23.976fps content the television is at
the same frequency.
