This patch worked for me with ......
mplayer -vo zr my.vob  which is great. What a difference a single line of code 
can make.
My Duron 850 mHz with 512 MB RAM uses 95% CPU to play 720x576 mpeg2 (DVD) and 
720x576 Raw DV.

356x288 mpeg4 is trivial at 20% CPU

mplayer -vo zr2 -vf zrmjpeg results in playback which is progress, albeit the 
playback flickers. CPU use seems to be only marginally less.

Well done, digging up the patch.
