hey rob, my urc6011 now works with x10, now it doesn't, now it does,now it doesnt, now it does!! last night i was playing with my MX-500 and it was being flakey with the ir543. so i moved the ir543 and now the 6011 works! but then it got flakey where i moved it to, amd moved it back to the original place(inside my entertainment center) and it works fine again. by the end of the night, my mx500 was fine, and the 6011 was flakey. this morning, they both work fine. any thoughts? anyone?
