I don't know how ff/avplay seek, so I cannot answer that.
Here is sample that seeks quite badly with the old demuxer, in
playback it takes several seconds for the seek to catch up properly,
because it seeks to an absolutely wrong position, while the new one
ends up much much closer to the desired position, giving near instant
seeking response

I've not had any complaints from users since I switched it over to the
new one, although I cannot say how much asf they really play, of
course. ;)
