I have no idea what you guys are talking about but have you looked at
mencoder and mplayer's filters?
There are quite a few filters and smoothing algorithms that you might
like to make use of to remove the jagged effect or other artifacts.
The bmovl filter might be helpful here.
Or is it some bug in MPEG or DVB implementation?
