I am posting this to hopefully help some poor soul out there that has run into this situation.
I have an interesting setup for my computer. I use a 42" Pioneer Plasma TV (PDP-4270HD) as the monitor for my Mac Mini and a PC tower used for other purposes. The Plasma is on a wall that serves as the support for the staircase leading upstairs. Behind said wall is a closet and crawlspace of sorts with very limited room. I mounted the TV on the wall after poking a 3" hole through the wall for cables, then piled Mac, PC, Tivo, HDDVD player, surround sound sub, and some other equipment in there, out of site. I use an IR blaster for the remotes to control the stuff and wireless keyboards and mice to control the PC and Mac (note - 2 completely separate and different sets, no KVM). The wireless keyboards and mice both use a USB RF receiver of some fashion.
I have been reorganizing things (just added a Wii) and had moved the RF receivers which had been sort of hanging from the TV in mid-air for a sort of line-of-sight to improve the range of the keyboards/mice. (I have struggled endlessly with this stuff)
I noticed that my plasma TV has this sort of Dead Zone with some tinkering. The Dead Zone is approximately 8-10" from each side of the TV, and probably the same front to back. This Dead Zone is a black hole for 2.4Ghz signals of any kind, even my iPod Touch's wifi drops when I get the TV in the way (WiFi router behind TV and low to the ground). So I moved both of the receivers well away from the TV and my range miraculously returned.
Now my Mac uses the Logitech S530 combo (very nice) and has no trouble with consistent non-lossy signal, and my PC uses another Logitech combo. The Mac RF USB receiver is a USB key of sorts plugged directly into the Mac and behind 2 sheets of drywall and some electrical/plumbing in the wall, but works just fine. I had to move the PC's cord-bound RF receiver to the front of the wall again, but this time about 24 inches from the TV. The reception is pretty good for both of them now....
Unless you're using them simultaneously. Which I do from time to time. I have a 19" LCD flanking my plasma on the wall as the primary display for the PC so that I can be on both computers at once. The PC's RF can screw up the Mac's RF and vice-versa (didn't notice before, such crappy signal). I don't know how to fix this, but at least things are working.
Worth noting is my Wii sits directly within the Dead Zone and isn't affected somehow (I believe Bluetooth is 2.4Ghz too). Oh well.
I hadn't found anybody with a computer with RF keyboard/mouse connected to a plasma TV, so I thought I'd document my troubles in case it is helpful.
I can only imagine WiFi, phones, and all other 2.4Ghz devices mess with these mice/keyboards as well, but this is my experience.
