Cheers for your reply Bob!!
Ok so i guess both scarts on the STB are outputs, one to the VCR and one to the TV. I will try your suggested setup for scart and will try plugging the xbox into the VCR on a seperate scart. This should allow be (in therory) to turn off the stb and have the VCR on AV2 and play on the xbox with sound!! I will try this later!! (This is how i had it set up before i got the stb.)
Otherwise its a "legendary SCART Video Unit from Argos" job until i get a better TV

!!
As for the RF signal i am interested to know what this "cable-splitter-combiner" unit is?? Does it split the cable before the stb?? Is this supplied by NTL or do i have to purchase one, and if so can u recommend any sites?
Ok cheers for your help!!
