MPEG-2 has software based decoders, but to get a reliable single stream
you need at least a PIII/600.

MPEG-1 is much more reasonable and the vbrick also does that....as well as
the Optivisions, the Minvervas and other such hardware based codecs.  The
Minverva, Optivision and the Vbrick all have appliance like devices that
either encode or decode and some have a combo of both.  Most are embedded
linux or similar OS's that are dedicated just that that purpose.  They're
pretty nice and all of them can be setup for either unicast or multicast.

The Optivision Pro Units (4RU rackable) can do multi destination unicast
with a huge upper limit (I've tried 20) of unicast destinations. The pro
units also can have multiple encode and decode boards installed.
