so.. am i basically screwed in trying to hide the box??
Not at all. Since I have 2 SA8300's which, of course, use the same code set, I use RF to control them independently. I use a URC MX-800 remote (IR & RF capable) and a RF basestation (MRF-200) that feeds IR commands to each device with a small, wired "emitter" that's stuck onto the display window of the DVR. You'll need to do something similar, but it's no big deal. Just make sure you get the right remote (one that's both IR and RF capable).
does the wired emitter plug into the IR port on the dvr? the only part you lost me on is the emitter.
oh , wait a minute. the "emitter" sticks on the front of the box, is wired into the RF basestation? ...
do the emitters come with the RF basestation.?
The emitters are little wires that plug into the back of the RF basestation (they're included). They stick onto the display window of the 8300 and transmit a low-level IR signal that no other component can see. It's the easiest and simplist solution to this problem of multiple devices using the same code set that I've seen. I've been doing it for years; works great.
