wireless TV link for pvr

Hi
I have a humax PVR and I would like to watch things that I have previously recorded on my tv upstairs. So I am looking for some kind of wireless Tv link, but it must be compatible with the humax PVR and will I need a new remote control or can I just take the original one upstairs. The main reason I want this is to watch pre recorded programs, as I already have free view upstairs. Can anyone recommend what I am looking for.
I also have concerns it may interfer with my BT hub is this true or not?

Thanks in Advance
