You did not say what your symptom is. Is it jerky video or no video or
something else?

Waiting for video buffers indicates a slowdown in decoding the video. Is
it mpeg2, x264 or something else?

I suggest go to the playback profile, edit and try changing the Decoder
to Standard. You can leave the renderer as vdpau.
