Running two Foxes at the same time...


Apologies in advance for a really dumb question!
I run an HDR-Fox T2 with custom firmware and an old 9300T which is now so unreliable that I have to replace it. I'm so happy with the Fox (largely because of the CF) that I'm intending to buy another - there's a few still available on Ebay etc. I need 2 machines because I often need to record more than 2 shows at once, but I don’t want the T2000 model because (as far as I know) it doesn’t run CF and seems unlikely to do so any time soon.
However, I can foresee a problem. If I have 2 HDR Fox T2s running at once, how do I stop commands issued to one Fox (via the remote) being picked up by the other?
