Sky Digital Digibox - channel change from a different room?

[Will__]

I have a Panasonic Sky Digibox for Sky Digital - I run cables from it into my study, which deliver perfect audio and video into my TV Input card on the PC.
Question is, does anyone know of any way of changing channels without trotting back to the living room and doing it?
I know you can buy a unit which beams tv and audio from one 'base' to another, and that the more advanced of these can also send remote control info the other way (back to the unit that is sending the audio/video stream), but this is an expensive way of doing it when I already get the audio/video perfectly through cables.
Any ideas? Otherwise am about to get busy with 3 mirrors if nobody answers this - should be fun for the weekend......
Thanks
Will

Having just read my post, I should add here of course that some people might say "move the digibox". The TV is of course in the living room and will remain there with the digibox. Or so herself has decreed.

You can get a box that plugs into the extra rf out on your sky box and will sit ontop of your study tv to pick up signals from your remote and relay them to your sky box There is a hidden engineers menu in the setup options of your sky box - i cant remember how to get to it at the moment. you need to turn the voltage on for the second rf out but before you do this you must make sure you have the remote extender plugged into the second rf out otherwise you could damage your tv. I got mine from my local tv store but you can get them direct from sky
