Well I was speaking of MPEG-4 in general, and was including xvid, H.
264 and VC-1 as MPEG-4 "variants". I was using the term basically to
mean "something "better" than MPEG-2".
Then there is "VC-1" which the Microsoft lawyers would want you to
believe is a completely new and different thing, but it certainly has
roots in the MPEG-4 systems. I have an on-demand box that stores 100
hours on 80GB and, much as I hate to admit it, it looks damn good.
As was pointed out, they are "at it again", trying to "get
proprietary". Such tactics never work in the end, but they keep trying.
I see the Chinese are trying to roll out a non-MPEG replacement for
the DVD format to avoid the MPEG tax. Even if they only wind up
selling to domestic customers that is a *lot* of disks.
