Hi All, I have an iScan HD hooked up to a PWD6. Sky currently goes through a RGB2YUV converter (but will eventually go direct into the iScan when I get the leads delivered that were delayed on my original order). Sky set to letterbox (I boost sky to other 4:3 TV's). iScan settings are letterbox input : 16:9 output using format 852x480 via analogue. The screens been set up for 1:1. To get this I had to fiddle with the h-size, v-size and clock phase on the panny. Overscan set to 4 and other little adjustments to centre the screen. Anyway, that's the background When watching sky I notice that on some frames where an object is moving little black horizontal lines appear in the moving part of the picture. It doesn't happen all the time, it just must be certain scenes this is noticeable on. The best example I can give is a recorded program from sky+, when fast forwarding you get the on screen image in the bottom left that's a circle with green blocks and they rotate round. Occasionally (depending on the scene shown) the green blocks have these black horizontal lines in them. Pausing the picture makes them dissapear so it's only movement causing it. Anyone know why I'm getting this? Is there any way to minimise / stop it or is it just something I'll have to get used to? I thought it may be frame rate issues. I was seeing this effect on 50hz locked to 50hz. I have since unlocked 50 to 60 (which improves the flicker) but I still have the occasional little black horizontal lines effect. I haven't watched that many DVD's yet and I haven't noticed it happening when watching from the DVD. I upgraded the iScan HD's firmware yesterday (and had to set up all the settings again after it all defaulted grrr.) but it's still there.
