I have a Loewe Vitros. Connected to AV1 scart is Video (composite via scart), AV2 is NTL DIgital box (di4001N via scart), haven't got software version number to hand, but can find out later and AV3 has DVD player (scan 2000 via scart). AV3 is set to RGB for DVD, no problems. If I enable RGB on NTL box then I cannot switch to analogue channels as they all show picture from digital box rolling across the screen. This is only a problem while the box is on (i.e. not on standby). Also if I enable video switching while the ntl box is on all analogue channels show what is on ntl box. With RGB enable on DVD, I have no such problems. At present I'm stuck with composite even though this nice tv is supposed to have rgb on av2. Advice would be most appreciated.
