Hi everyone. I just would like to open this topic on my ghosting investigation of CLD 79 connected via S - Cable to my new HD Panasonic Beamer PT-AE 5000. Tomorrow never dies Japan LD had 4 lines of ghosting noticable on a big screen.

Is ghosting a issue in LD world ? Why does it happen? How can it be avoided or corrected?

Thank you

The issue isn't with that LD or that player (both are great) and I'm sure the TV is very nice, but the combination of the two is probably causing the issue.

A picture would be helpful, yes.

Ghosting does appear to varying degree depending on the player, the worst I've seen is with the LD-V8000. I've never seen 4 lines of ghosting, I have seen 3 lines. I would try the composite if your Panasonic has a composite input. This could be signal reflection due to the cable or the 79 and pana impedance matching. I would change things around to see if you can get this to vary or greatly reduced. This is like the white smear issue. Not everyone sees it or is bothered by it.

Thank all for responding. Picture has 3 - 4 Ghosting lines, not overall though! Subs have only 1. S-cable is a very good thick isolated quality cable, but it's 10 m long.

Have you tried turning OFF the DNR on the 79? Sometimes digital processing in the LD player and then again in the monitor enhances the issue. This is probably something you will have to live with as I have seen slight ghosting on about all players to different degrees. You may need to try different players if this bothers you too much. By different I mean going back the the LD-S2, CLD-95, or CLD-97 Elite players if you like Elite players or try one of the HLD Japanese series. The LD-S9 looks just like your 79 so don't try that Japanese model.

I don't think he needs to "try" any $2000 players to fix this issue.

The example pictures aren't that great, but it does look like maybe the TV's edge enhancement or sharpness settings might be causing this. With LD you are going to want all that stuff turned off or way down. You can't create clarity out of thin air without introducing flaws. Also, try using composite instead of s-video.

I'm not sure if this is anything, but I'll throw in my two cents. Mostly all analog formats look really really bad on LCD TV's. Truth is, I only think they look good on CRT sets. Maybe this can be part of the issue, I am unsure.

others will answer this better than i, since i still use a CRT.
BUT i believe you need to adjust your settings on your TV, get a test disc / setup disc
and get it set.

looks like you have too much something, sharpness or contrast, you just need to adjust it.

Thank you all. First of all I have to make a few issues clear: I bought my CLD 79 trough US Ebay without a remote which I have a very hard time to find on E-bay. I am unable to control NR but as far I can see on my Panasonic CRT 28" TV the picture is almost too sharp with S-Video, REALLY enjoyable beautiful. So I suppose, NR is in off mode for sure.
The Issue with my new LCD Beamer (front projector) is different due a big picture on my wall. More weak things are noticable and it takes time to adjust the screen for every single LD movie. The photos I posted are made with Iphone 3GS (I don't own a real camera) and I made sharpness & detail clarity stronger for you guys to see lines of ghosting.
I was experimenting with composite input to my HD Beamer (a very fine machine by the way - I would recommend it to all of you, both 2D and 3D are great and a picture adjustment can be very easy or also if you like it very complicated) and I have to say that the picture of a composite signal was rather blurry and unsatisfiying. S - video connection made me smile immidiately, it was much much sharper and detailed but sort of corny with deinterlacing artefacts, starecase-lines and ghosting lines (sometimes). So that means that my beamer is too modern to handle LDs really well and I need something like this:

1. an external A/D converter to convert analog signals as good as possible to digital signals to be sent to a modern digital high quality LCD beamer
2. external de-interlacer
3. external upscailer

Now, Kurtis and/or Signofzeta if you like please tell me your opinion on A/D converters in general, nobody talks about them. Are they most important part of getting the analog picture right in a digital age? And yes, I read that site "watching LDs in digital age" which is very well written but doesn't say anything about A/D converters.
Maybe I can enjoy all of those 3 using a brand new Pioneer AVR CS LX-56 K which also has a Marvell Q-deo system for picture processing. But I can't find any information on Internet, how Q-deo is actually reacting to LD Picture. Somebody here in forum tested it trough ONKYO AVR and was completely blowed out (positively).
I will get my Q-deo AVR from repair (it came new and was unable to start) in 2 weeks time. Then I will test it and post pics here. I'm very curious how much noise and detail it can handle in right way.
Thanx for answering all, great people here on LDDB forum. I'm very happy to be able to join.

I've avoided the issue completely by sticking to CRT in my home theater. Sorry! :)

I run a CLD-97 straight into my Pioneer Plasma. The Pioneer Plasma is one flat screen that does a very good job handling NTSC sources. You need to talk to others that use scalers. I know the high end DVDO unit are supposed to be good but I've never used one to verify.

On eBay there are people selling programmable remotes programmed with the CLD-99 codes which is the same codes used by the CLD-79. Everything is set to standard when you plug in the unit. So your DNR is half way between min and max. Cannot remember where the 2D/3D setting is at. If you are getting a better picture using the S-Video on your analog set then it has a poor comb filter or it is having issues. The majority of the time the composite is as good or better than S-Video but not always.
