Hmm, you must have an older or cheapo VCR if it's only got one SCART :p

I'd be tempted to play with the VCR RF rather than the STB. That way you are fiddling with and affecting something you own. You should only need a very small adjustment to change the clashing frequencies. It was something many of us were told to do when Channel Five was launched as that often clashed.
