IIRC, you're still missing a piece of hardware. You need an IR blaster/transmitter. The receiver can only help you learn remote codes in your scenario. The blaster sends those codes to your A/V components. Maybe you've seen some discussion around here about putting an IR blaster on an n800. Forget about that. You need an IR blaster that either connects to your network (expensive) or you need one that connects to a compter (not your tablet) via some serial port. Preferably USB. I recommend visiting this page at the irreco project. There are some diagrams that may be helpful. And just in case, a transceiver is both a transmitter and a receiver.
