Can you tell what type of STB you have - there should be a label on its bottom with a model number.
Older boxes only support an 'obscure' infra-red protocol for which you would need a
Digi-Eye infra-red remote extender. Newer boxes also support the 'standard' infra-red protocol and, for these, you could use any old videosender which could well be cheaper (and would have the side-effect of sending your video signal wirelessly too). If you want to connect to several devices (eg. cable, vcr, dvd) then you could check out the
Digisender x4 Gold.

RIR100 which would have been ideal for
