Hope someone can troubleshoot this for me I was watching the Criterion Silence of the Lambs which told me something is really wrong, as half the film is very dark, and all the dark parts are swaths of grey and red with no detail. I don't usually watch live action stuff so I guess I never noticed before. But I put on another movie today and the dark areas are the same solid blocks of color. My setup is really complicated, so I thought I might ask here in case anyone has dealt with this. Thanks!

Okay, so here are the shots from Silence of the Lambs (the same thing happens on other discs, CLV and CAV). I shut off all of the player's filters, etc. The only thing in operation between the LDP (R7G) and the TV (Sony Bravia KJ-65X9300D) is a Lumagen HDQ on default color settings (lower color settings fixed it about 50% but for many films that setting looks like a used-up 70s film). The weird effect seems to affect shadows the worst. Here, the space between Jodie Foster's face and her hair near her eye is a solid grey band. Here, very close into her hair looks like an amiga demo effect.

Or are you using the "d-ext" function on the player? If so, turn it off, reset brightness, and see if it still happens. when I turn on the D-EXT on my R-7G player, I get better black coloration where it should be black details on tv screen. I always use the d-ext feature.

why did Pioneer add this feature to R-7G and other players if D-EXT fooks up details in picture? all filters switched off during film watch should give an unmolested picture quality.
D-EXT should improve some things in certain occasions?
although I use high end screened cables with gold plated Y/C plugs, playing NTSC LD, (never the same colors) looks sometimes a bit bland or faded on my TV! with D-EXT enabled I must say that picture quality improved on my old telly box.

Yes it was added last year for analog sources: http://www.lumagen.com/testindex.php?module=radiance21XX_updatesProduction 030517- For 21X4 adds PC/Video level setting for composite and svideo sources. Adds audio mute delay for analog video sources.Julien

So, From the Radiance, PC is 0 IRE and Video is 7.5 IRE. Jim Peterson wrote: Note that we posted a new release today for the 2144 (030517). It allows you to select a 7.5 IRE black (“Video Level”) which is the normal mode) or 0 IRE black (“PC Level”) used by some LD players. When 7.5 IRE is used for a player that actually outputs black as 0 IRE you get “crush” for levels below 7.5 IRE (as one would expect). 0 IRE should be used on PAL and Japanese NTSC post 1985. 7.5 IRE on USA NTSC. How do you guys manage playing alternatively Japanese and US NTSC LDs? Switching between different profiles on the Radiance? I've plugged Input 12 for LD Player and managers different profiles for Audio/Subtitles masking from MemA to MemD. Maybe a quick win would be to plug the 2nd Composite output of the LD Player to Input 11 and copy all MemX from 12 to 11 then set all 12 MemX to 0 IRE and all 11 MemX to 7.5 IRE? This is you end up with a identical video/audio configuration on Video 11 and Video 12 but the difference is only the black level? Julien
