I get dark/white crushing on my 36PD30 via RGB when using my Pioneer 454 DVD player. Some other users have similar problems with other DVD players but some models seem fine. I do not have any problems with the RGB output from my Sky+ box. I read somewhere that RGB dark/white crushing can be caused (on a Philips TV) by the RGB output of the DVD player being too high. So I tried looping the DVD player output via the Sky+ video pass-through. The results were excellent - RGB quality but without any trace of dark/white crushing! Watching LotR last night I was amazed by the PD30s picture quality. This would explain why some users see the problem and others do not. (My DVD manual does not state what the RGB output level is - but I assume that it varies from model to model.) Note that I have also seen the dark crushing problem when using component outputs - so it is not just an RGB issue. (Connecting both component and RGB outputs simultaneously may reduce the output from each and this may also cure the problem but I have not tried this.) This problem was my main gripe with my PD30 - so now I am a happy man. I still can see the interference lines on black backgrounds on DVD (not on Sky+) but only if the brightness contrast is above about 65%. I prefer these settings to be lower anyway. Using an Avia set-up disk confirmed that the brightness/contrast should not be this high. I also checked with Avia that there are no dirty colour patches. Only major issue that was highlighted was the huge amount of overscan - about 5% on both sides. I'm wary of the Avia disk turning me into an AV hypocondriact - it can highlight so many things that are "wrong" e.g. my set has a blue chroma delay - but I have no idea what this means or what difference it makes.
