This all depends what you want the box to do, if you are looking for x
hundredK HDTV set-top boxes, a videodecoder is exactly what you need. Don't
know what Pace is using in that Premiere box, but they do have a track
record with the equator chip.
Interesting website, btw...

Plus ofcourse the fact that you can run a full linux OS *with* MMU
support and process protection on the Equator board, since it is a SoC.
That in itself is a huge differentiating factor against your Blackfins
or Sigma chipsets which may not have MMU or may be only a video decoder,
and need to be integrated onto a board.
Indeed we don't have this board, but nevertheless our current h/w
platform is fairly similar from an OS point of view -- with the tools we
have and the fact that we can debug over the network with a process
protected stack running standard libraries means that while my old
buddies are still jacking around with their JTAG i/f, we can move a box
from baseline to prototype in a few weeks.
I'd be very interested to see such a list of chip (and SoC!) vendors for
H264/vc1/whatever myself.
