Well Im quite prepared to yield to the majority view on this, just
going by the discussion here over the years I had come to assume it
was much less of an isue now. Like what spec are all the machines that
cant play baseline h264 at 320x240 or similar resolutions? These days
Im assuming that the bigest compatibility issue is people who dont
have quicktime or an alternative player/browser plugin installed at
all, which makes mpeg4 just as inappropriate for them as h264, and is
an issue largely overcome by the use of flash format.

I am very interested in the artifacts problem you highlight, I would
like to work out what this is. Got any example footage? Does it happen
even at 320x240? Its nothing to do with interlacing is it? 

The other factor that made me assume this is less of an issue is the
number of people using Apple's ipod presets, thus using h264.

But yeah, 3ivx & similar are certainly capable of getting a lot of
quality out of the mpeg4 format.
