That's an incomplete list, too... As for the rational, Michael mentioned 
turning on special codec workarounds by fourcc's.

I dunno, how do you accomplish this right now with AVI? As far as support 
goes, I'd say AVI is doing pretty well.. Even on set-op players...

Now, believe it or not, coming up with a new system against the AVI mess, 
makes the situation WORSE, not better, because players would have to 
maintain multiple lists instead of one in order to support several 
formats.

As for the actual list to put in the spec, for all I care you can grab the 
list from riff.c and use that.
