Thanks for the reply, but I already have the digital adaptor on one of my sets. I did mean a smaller version of the regular or HD STB so one can still access the guide, etc.
Unfortunately the only STBs, at least at his time, that support MoCA (needed for guide, VOD, widgets, etc.) are the large QIP series. Comcast uses the DCT-700 with guide and VOD but with a different back communication path than Verizon.
