That was an problem in alsa-lib 0.9.x and previous versions. There has 
been a two line patch for this problem which is included in alsalib 
1.0.0pre1 and all later versions. Nothing to do with mplayer. Just for 
the protocol :)

I also have problems with oss-emulation and mplayer on my ice1712-based 
Terratec DMX6fire (skipping in video stream takes about half a second), 
but this also seem to be an alsa issue, not mplayer's.
