With my setup, I still only have one HD output (TV1) and one SD output (TV2). So we cannot be watching two different things in HD at the same time, but that limitation works for my family. The TV1 output is connected to one HDTV via component and two other HDTVs via HDMI (using the cables and splitter/switcher listed below) so it can drive up to three HD televisions. TV2 is connected to all five televisions in my house (3 HD and 2 SD) via coax. Most of the time our family is watching the same programming, but when we aren't one person is usually watching one of the SD teleivisions or can live with an SD signal on one of the HDTVs.
The IR distribution system I have is customer built, but there are consumer product options from companies like Xantech and Buffalo. I have an IR "eye" in each room with a TV that relays the IR commands to an IR blaster near the 722. My setup is a wired setup, but there are wireless options too.
Here is a link the monprice's HDMI cables:
