Actually the cvs of X runs itself at a sub 0 value by default.  This is not a 
debian specific thing, it runs S<L

I tried benchmark at -20, -5, -1, 0, 20     I found that with almost no cpu 
usage ( i still had konqueror open and kmail and freeamp and numerous Eterms, 
 and gtk apps; they all dont use any cpu when not actually rendering or doing 
something active) 0 and 20 give you about the same numbers.  0 of course is 
your most optimal here.   As for being perfect, it's not like i'm dropping 
frames on any movie at any size ( noting size doesn't matter here since no 
more cpu is used if it's at 1x or fullscreen), it's that it is being 
efficient.   
        I'd like to use the benchmark program to figure out where aviplay 
development can focus it's work on to increase efficiency by lessening sync 
time and such and the amount of cpu used for actual decompression.   To 
really do that though you'd have to test it on different systems using the 
same clips and look at the general info, the wide range of systems should 
cancel out the extremeties and give you some real program performance data.  
I think 2 clips should be sufficient unless data shows it to be unnecessary. 
one with a simple animation and another extremely complex.  I think we all 
agree that the format should probably be in div3 and maybe asf since those 
are the most common media used with avifile.  You really cant get as much of 
a performance increase as one would like though because the codecs are closed 
and that's that.   As far as i can tell, the cvs is doing a good job compared 
to the stable version and hi fives to everyone in development.  aviplay beats 
MS Media player easily in avi playback and seeking, i mean obviously.  Not 
sure if it'll ever be possible to do the hardware filtering mediaplayer does 
to make edges less jagged, some kind of blurring, but that's fine.
