Last week I had a problem with our Sky box spluttering (digital squelches and blocks) when we moved it from AV2 to AV1 RGB. It was suggested that the scart leads may need replacing with better 'fully wired versions'. Fully wired scarts now purchased (at premium rate) but alas the problem still occurs. Feeding Sky into AV2 via scart is no problem, switch it to AV1 (even without selecting RBG output on Sky) and the spluttering starts. Note that the PS2 runs happily in AV1 or 2. 'Please' - a man very distraught! - any help much appreciated.
