Sat requires direct cable to the receiver without any spliters or switches in line.
After that, if you want HI Def over the HDMI output from the receiver, you'll need to run HDMI cables from the receiver to the TVs, that's if the receiver has two HDMI outputs, if not you might try an HDMI splitter, but you'll still need to run those cables. Not as simple as jacking it into your existing splitter.
