I'm having exactly the same effects in my full featured card! I get the
pauses in video, and in audio as well.

I've tried these versions too, but not much difference. I'm tried also
several versions of mplayer.sh.

I've tried lavc=5000, seems to help a bit, but jerkiness is not totally
gone. Also setting maximum x-resolution to ~500 seems to help a bit. I
have 50% CPU load, so it can't be that.
