An RF solution would likely work, but be somewhat costly. The MyTV  
site has some RF devices, including what appears to be an IR repeater  
that would probably work.

Several outfits make IR repeaters of various types, some wired and  
some RF.

If it were me I would probably try just extending the cable for the  
Hauppauge IR receiver. An extra 30' may or may not cause trouble, but  
it would be the cheapest solution and if you are running wires anyway...

I'd use an unshielded cable to minimize capacitance to ground  
problems. If you get RF pickup problems you could try a .01 or a .1  
uf capacitor to ground and/or a series inductor.
