I'd disagree to some extent.  An intel chip of the 266 MHz starting point
can usually handle MPEG-2 decompression in real-time without dropping
frames if that's all it's doing.  A 366 MHz processor in a laptop can do
MPEG in Linux at least without hardware help, though in some other evil OS
there is help from the hardware on this particular notebook.

A VIA chip around 900MHz or so should be more than adequate for MPEG
video.  It should do DivX fine as well.  More complex formats (which
nobody is seriously using at this point in time) are out, but unless there
is a major compression breakthrough, DivX video is currently about as good
as it gets for quality and compression ratio.


Of course, with hardware decoders, a dinky 50 MHz processor is almost fast
enough to be useful for some practical purpose.  Like presenting a simple
GUI to the user, perhaps.  But I wouldn't expect you'd know much about
that, right?  =)
