I would like to distribute the HDMI signal from a 722 to other tv's nearby. Is there a distribution amp that allows this? How does it work?

Several companies have started advertising their wireless HDMI transmitter/receiver systems that will be available late this year.

The ones I've looked at will all work with any receiver that has an HDMI output. The various models support from 2 to 4 extra TVs but the early models will be expensive, up to a $1000.

The only advantage I see is to be able to watch the same HD program from several locations since the 622/722 only have one HD output.

Might be simplier to get one or two more HD receivers from DISH, for now anyway.
