The 5800 only works through RF? No IR sensor at all? Well, there are the MX-600 and MX-800 remotes from Universal Remote (available online from places like
BlueDo ) - they will do both IR and RF, and the MX-800 offers a computer interface so you can download other people's system configurations. The MX-800 is a bit pricey ($250 on eBay, more through more traditional channels).
