I may have a chance to get a Pioneer LV-4300D, as shown here http://www.laserdiscarchive.co.uk/laser ... -4300D.htmOne thing I don't understand - why does it have RGB outputs? My understanding was that the signal from a laserdisc is always composite, so presumably the player is decoding the signal and assigning it to the RGB channels in some way. Is it simply for compatibility with some types of display? If so, would there be any advantage in using these outputs rather than the composite signal on a display that supports both? I don't yet know what other outputs it has, since it was sold in Europe I'm guessing SCART and composite, stereo sound, possibly digital sound outputs. I'll post more once I know.

Just a shot in the dark, but I imagine since the machine was pitched as a player and interactive/multimedia machine, RGB could be beneficial at least for compatibility with certain monitor/av setups?

Pretty much what I was thinking - my first thought was something like a computer monitor but that doesn't quite fit with the PAL/NTSC video selection pin, so probably the outputs are intended for display panels, projectors, etc. I haven't come across a specific pin for PAL/NTSC selection before, but I'd imagine there's something out there that uses it.

Just finished trying this. The good news is it's PAL and NTSC, the picture is OK though not quite as good as my CLD D925, and it has no trouble with disks that have analogue-only or digital-only sound. The bad news is that the outputs are a bit basic - composite video, analogue sound, and the weird RGB output I mentioned earlier. No SCART, though that isn't a huge problem, no digital sound, and of course no AC-3. But overall it ought to be fine as a backup player, which I may put in another room where I have a smaller TV, if I can find enough shelf space for it. And in the unlikely event I ever find an arcade game or data application that needs computer control it has the serial port, external sync ports, EFM output, and barcode reader socket.
The sad part of this is that the guy who sold it to me inherited it from his father several years ago, along with a big collection of laserdiscs. Which were stored outdoors in a garden shed, and stolen a couple of years later when someone nicked his bicycle! I'm willing to bet the thieves thought they were taking LPs, and dumped them somewhere when they found out they were weird. But I suspect the price would have been a lot higher if there had been discs, so never mind...

And the bad news is that the RGB output either doesn't work or has pinouts completely different to the ones shown on this page: http://www.laserdiscarchive.co.uk/laser ... -4300D.htmI don't really have any way to test it, so I'm cutting my losses and sticking with composite, and hoping that the cable maker will give me some sort of refund if I return it - the pinouts are right for what I told them so it isn't their fault it doesn't work.

Hi, I checked the forum in search of someone who also tried the RGB port on the LD-V4300D and it seems and I'm not the only one having trouble with it, unfortunately. Here, I've tried buying a special VGA cable that has 15-pin on one side and 9-pin on the other, the exact needed number to connect the player actually. But as I've tried that way on my old LCD, which has a 15-pin VGA port, the video signal wasn't recognized at all. I thought for a second it was a faulty unit, but then I tried the composite and it worked (it worked damn well!). So, I was thinking, since I found the original scanned manual of the LD-V4300D, I read that the RGB output was "0.7 Vp-p 75 Ω". Does that mean the player needs a specific cable with those specs to work, or is it a feature that is simply not working, like a defect on the whole line? You can check the manual's PDF attached to this post

I agree, but two things:
1) it would be nice to hear a reliable first hand account of what the output looks like. It can't possibly be good but it would be interesting if it wasn't a absolutely hideous because that seems almost guaranteed.
2) if everyone searched before they posted there would be like six posts a year. Also, 100 people getting all their information from a single thread is probably not a great idea. That's how a lot of really dumb conventional wisdom procreates. Sometimes you can find totally false popular rumors that originate from a single first hand account. Think about how much confusion there is over laser rot and how it gets hugely overrated and assigned to almost any symptom. Also, consider how popular opinion changes and time goes on. A lot of technical advice given in this forum and others I go to has suddenly been supplanted when new products come out, or maybe just come to light, like the almost revolutionary discovery of the usefulness of DVD recorders or the DPS-290.
It's not like this is some Sons of Anarchy forum with 1000 posts a day anyway...
