>  format to go across a short coax run to an HDTV?

>  Obviously the chips must exist; all the DOCSIS cable modems use

>  The advantage for MythTV owners is an HD display connection that

>  scenario, it might be possible to do 1080P playback from a
>  very low powered device. Constructing OSD might be a problem.

>  only considered to be of use to TV stations. But I'd be pleased
