 	In particular, search for a few posts made by me.  I've explained 
it a number of times.

 	To answer your other question, you can change some of the modeline 
parameters on the fly using an older util called 'xvidtune'.  You cannot 
change the dotclock or total raster from it, but you can move the visible 
part of the raster up/down/left/right.
