Well I took the plunge and bought this disc to see what all the fuss was about and I have found it very informative but the basic video setup regards my PV500 has not turned out as expected and wondered if anyone could share their findings or knowledge. I used a Panasonic es10 DVD player both via component and RGB. This player does not have any brightness / contrast controls so I figured it was one less variable to bother about. Initially I used Cinema setting and then Normal ( why is it that cinema seems to boost black level detail yet appear softer) anyway brightness ended up at approx 68% and color at about 65%. Contrast however has me stumpted as I cannot see must difference except at off and full on and the blooming does not seem to appear except at almost full on. So I settled on 40% but without the discs help I must say. As for the sharpness I find that when set correctly according to the disc in reality it need a couple of clicks further up to avoid everthing looking blurry. The colour setting does appear to look good and there is no problem with the blue squares when flicking between cool normal and warm so I've settled on normal. Cant believe the brightness setting is correct and would welcome advice on setting contast. I feel my other question on setup regards the fact that my other DVD player has its own picture controls which would surely confuse the results is best left to another day.
