I would like the 2nd UHF/AV output on my Sky+ box to go to my portable telly in our bedroom. I don't want to run any coax anywhere though. I have a digisender that broadcasts the scart signal to my portable telly.

I'd like to use the 2nd AV out on my sky+ box as I can set the aspect ratio for the 2nd AV out to be different to the standard aspect ratio.

Is the any way I can convert the AV signal to scart so that I can broadcast it? Is it just a case of connecting the AV signal to the composite pin on the scart?

TIA
