Video senders?

I have a sky+ box and a TV in one room. Now I want to move the TV to another room, but leave the Sky box where it is to avoid a lot of cabling. I've looked at Video Senders, which seem like a good solution, but I want to be sure to be able to change channels etc. from the new location. Also, the infra-red receiver on my Sky box is dead. Will the video sender work anyhow, as it connects with a scart.
