> Yep - PAL vs NTSC, as you guessed. Also, the RF modulator for the UK is different from the one used in the rest of the European PAL countries, as the sound subcarrier frequency of PAL-I differs from that of PAL-B or PAL-G (I don't remember which one is which; I think one of PAL-[BG] is VHF and the other UHF). I have a VIC-20 RF modulator that was bought in the UK, and when I hook it to a TV, there is only noise in the sound output. I don't know if there really is a PAL/NTSC issue with the modulators. It might just be that the sound subcarrier frequency and the modulation frequency matter; the PAL/NTSC colour encoding difference is already in the composite video signal, which the modulator should not need to decode in any way.
