[M4IF Technotes] HD decoders?

[Eric Grab]

The DivX 5.03 encoder and decoder are indeed compatible with MPEG-4 Simple Profile and Advanced Simple Profile video.  The bonus is that the DivX decoder will decode other formats, such as version 3.11, which is not MPEG-4.  Is there a video stream you cannot decode with DivX 5.03?

Can't you turn off all the extra features that DivX uses for differentiation? Anyways you'll need to do some type of pre-/post- processing regardless of what codec you choose.
Or another way to place the question. WHAT makes DivX not "pure" MPEG-4???

Tom,
    Encoding isn't a problem.  I'm using Sorenson Squeeze, which can make
compliant HD MPEG-4 without breaking a sweat.  It's the decode that's a
problem.  I don't want to do a DivX decode, since it isn't pure MPEG-4.
