Daniel,how would I use a digital camera to confirm it sending IR? I have no televisions or fluorescent lamps in the room. The IR 543 is just for the X10 stuff, it hesitates even when aiming it directly at the dvd/ld players. Last night I swore it took an hour to spring to life. Had the wifi on and all the web browsers were working,tried to figure out how to defeat the epg but could not. Now this morning it works fine right off the bat.
