That's likely the core reason - the deinterlacing in a commercial
broadcast quality transcoder is going to blow the doors off whatever
you find in the SOC in your consumer television or other hardware.
Doing progressive also makes it easier to transcode/transrate the
video for mobile devices (since mobile devices typically can't do
interlaced video and whatever crummy transcoder might be built into
the STB won't have to have any deinterlacing functionality).

Of course, the deinterlacer in their broadcast quality transcoder is
also going to do a much better job than whatever you're getting via
VDPAU, but that's just a side effect and not something anybody at
Comcast is even thinking about.

It's easy to say "1080 > 720", but in reality it tends to be a much
more complicated issue with regards to which is going to provide
better quality across the large base of content types and viewing
devices actually expected to render the video.
