I went with this
Keydigital

Pretty sure the lower end model would function the same.

This unit doesn't scale, I connect to my TV and let the TV do the scaling.

I then connect Coax into the 861 and setup several phantom sources.

Works great.

Only issue I have, is that w/ a Tivo Edge, on some channels, if i skip around a lot, Cinema will sometime sync to Discrete.
