How many external IR emitters can one USB-UIRT support. Is only has one jack but I was thinking that maybe it could be split to more than one emmitter. I know that the same signal will go to all the units but when you use a hand-held remote pointed at the rack, everything in the rack receives the same signal and they just ignore what doesn't appy to them. This being the case, could I possibly use one USB-UIRT connected to my computer and use this modified external emmitter and control my TV, my receiver, my external HDTV receiver (I only have a single tuner in my computer and I may want to watch something else while it is recording), and my stand-alone DVD player (so I can play encrypted DVDs. Currently, my equipment doesn't have RS-232 control. As I upgrade my equipment, then I will be looking for this as a feature. But for the time being, IR is the only control available.
