It looks like you're searching analogue, but it should be PAL I for the UK (presuming all your gear is UK spec). This is to do with the sound carrier. PAL B/G will give you a picture but no sound if the transmission from the VCR is PAL I.
Band C is 46-890 MHz, which is what I'd associate with digital cable TV (hence 'C' for Cable). There used to be analogue cable TV transmissions, but I think it's mostly digital now, so I wonder if the TV is expecting to pick up cable transmissions rather than analogue terrestrial? (Disclaimer: Analogue cable is something I know very little about other than Milton Keynes had analogue cable piped to all the houses.)
Band S is for Satellite reception. Some TVs have a built-in satellite tuner. There'll be a separate input for the signal cable for satellite, so if the TV is getting Freeview then I know you're not connected to the wrong input.
What is the make and model of the TV you are trying to tune?
No. Band C is broadcast channels 2-12 and 21-69. Band S is for special cable channels S1-S41. These are located on frequencies between the broadcast bands. Satellite option would not be offered in an analogue scan.
