Has anyone setup the AV8 for RGB switching? The manual shows output pins for 4:3 and 16:9 switching use (Page 11 on the ring of the I/RGB trigger output) - I just can't see any INPUT for these switching signals (ie from the output of my Sky+ or DVD player's RGB scart) and I've no idea how it makes the decision! Currently the TV auto switches the aspect for 4:3/16:9 signals from both Sky+ and DVD when they are directly connected via SCART cables - would I loose this if I routed the signals through the AV8? I'm assuming its done using Pin 8 of the Scart, though I have had it work from R2 DVDs when connected via S-Video using line 23 switching (which I guess may still work if using RGB). Also does anyone know anything about software upgrades - are they only available if I go back to my dealer with a specific problem or do Arcam notify registered users when new software versions become available?
