a) SD material is REC609 (normal)
b) HD material is REC701 (wide)
c) The RGB range thing is definitely for computers. RGB or Component signals for video should use the 16-235 range. So I guess I should turn that setting back off on my HDDVD player though I suspect it does nothing when connected to a video projector.
It also states that there is a problem playing upscaled SD material because the display cannot know that the source is SD (at least not if you are connected by a component video cable) In other words, if your projector is set to 1080p, it will tend to assume the wide space... unless it is a VW60 and gives you a button with which to choose
This leaves an interesting question which I'm hoping someone here will know the answer to. If an upscaling DVD player or HDDVD player plays an SD disc, does it, or does it not translate from the SD to the HD color space? My current observations would suggest not, in which case viewing SD material with Wide Colour enabled on the VW60 is a definite no-no.
P.S. Watched the pianist (HD) with OmarF's settings last night. Definitely looked very cinematic, and no noticeably wrong colours and a nice color termperature - these settings are growing on me. However, I do think something might be gained (for myself, at least) in the darker scenes by re-enabling auto-iris. It was designed into the projector for that purpose, after all! The general view on these iris devices seems to be that whilst it is a bit of cheat in terms of the full on/off contrast figures, they do give a genuine benefit with real material too. Setting it at manual 37% with low lamp is basically just running the projector with a very low maximum lumen output. Makes sense if you have a screen with a gain of 6 in a dark room, but perhaps not so good for my setup. I'll keep playing and let you all know.
As a general principal it seems to me very unlikely that one specific set of settings will be the optimum for everyone. Dare I suggest that we should, perhaps, discuss principles here as much as actual numbers? For example, does anyone know exactly what the 02/UF/DE switch in the service display engine menu actually does?
P.P.S Obstler - are you watching HD or SD films??? If SD DVD then your violet/purple lips sound exactly like the sort of thing I've seen with SD material - just switch back to Normal color space and I expect all will be well.
