Yah composite is the single yellow rca with r/l for stereo sound.
My pioneer elite dvd actually works better component video than the hdmi

Don’t wanna be part of that misinformation crowd there Doug! 😀

Allow me to clarify the difference:
Composite video carries all the video information (brightness & colour) over one wire.
S-video carries the brightness & colour information as two separate signals, over two wires.
Both require the addition of L/R wires for the audio signal.

You're joking right, it's shorter than this one 🙄 Ok, fewer posts, maybe a longer read, definitely a better one......so far 😉
I’ve used all three (composite,component,and s-video)
Best for my setup is Component video by far (imo).....like I said it bests hdmi for picture quality in my setup. I suppose that just means my tv isn’t as good as my DVD player for digital video conversion?
To answer your question about why the questions are becoming more basic, let me relate a bit of my own experience for you...
I used to teach basic electronics in an industrial setting. My job was to give a 5 or 6 week prep-course to get people started before they were assigned to a full technician as an apprentice; for our product lines, of course.
When I first started we were hiring kids right after high school. Most of them had the most basic basics --Ohm's Law, Watts Equations, Voltage, Current, etc.-- and most of what I was doing was helping them understand the more complex schematics and doing some disassembly/reassembly training. The first few years, almost everyone went on to be apprenticed and a few of them made it their life's work (as I did).
By the time we shut the course down in the mid-1990s we were hiring graduates from the local community college and most of them didn't have the first clue. They were clumsy with tools, didn't grasp the concepts. In fact in the last course I taught, I dismissed over half of the class in the first week because it was obvious they just couldn't do the work.
As to why this happened, we can look at changes in the edcucational system. For one thing, Science courses --including Physics and Chemistry-- were now optional and kids simply weren't taking them anymore. This level of education had moved up to universities where the focus was increasingly on programming and other skills not directly related to service. It became very hard for us to find candidates who were even interested, much less capable.
As your other thread touched on, the growth of search engines also fostered a "tell me the answer" mindset in which understanding and actual learning were disfavoured in favour of simple "Change R313" kind of answers.
Fast forward to now ... we have two generations who expect to punch a few keys and get simplistic answers to complex topics and have no interest in learning beyond that.
In this growing atrophy of tech skills also comes a growth in magical explanations, concocted to fill the gaps in their understandings... Gaps that used to be filled in during grade 10 and 11 science.
As a result of this we now have two generations who think they know stuff they absolutely do not know and who get all bent out of shape when it's pointed out to them.
One incident from a couple months ago brought that one home for me. I was helping a friend move. When it came time to pack up the stereo, computer and TV, all of which shared a common stand, the young guy helping us just grabbed everything and put it in a box, willy-nilly. Then when it's all over at the new place, he tells me "I can hook this up. Ordinary people know how to do this stuff too. It's not hard"... so I said "Go Ahead" and went home for the day. Well turns out he did a great job. He managed to hook up a rechargeable keyboard light backwards and it went in the garbage when the battery died and he didn't know how to fix it. Then he got the 24volt supply for my friend's amplifier into the side of her laptop and exploded the battery. ... But, even after that, he still claims he knew exactly what he was doing.
So, that's kind of where we're at right now... People are clearly becoming less and less tech savvy over time, and more than a little bit dumber, too.
Of course all this also makes them easy prey for the charlatans selling the garbage that is the subject of this thread.

“More than a little dumber” sad but true!
Our youngest (28) reinforces it every time I talk to him! 😱

Thanks for your full answer and I agree. Regards the above, he was probably never given any negative feedback, or if he was, didn't understand it's purpose 😉
But I meant this thread Cable shield as a Faraday cage 🙂
Matt you hit that nail square on the head!
That’s what ruint the youngest.....sports where both winning/losing teams get trophies, positive reinforcement even if they were screwing up in Royal fashion.
The wife wouldn’t even let me yell at him.....and then we found out one of his friends turned in his parents for swearing at him, the parents had to go to anger management classes!
I calmly expressed to him that if he was to try something like that mama would no longer be able to protect him, and that I’d get out of jail soon enough!
Seemed to get the point across, but yah......still ruint!

@ScottJoplin...
To answer your question about floating shields and faraday cages...
First be aware that farady devices (copper lined rooms, emi-shields, etc) only work as such if they are grounded.
Absent the ground the phenomenon of re-radiation --where the screen itself acquires and echos a signal-- becomes a very real risk. In this case the shield on an interconnect can and likely will act as an antenna, feeding common mode noise into the underlying signal wires.
Even when grounded at one end, as I previously explained, the shield tube can easily become an antenna where it is an odd multiple of quarter wavelengths of the interference frequency.... In fact that's how you get "Breaker Breaker One Niner" blasting out of the speakers of cheap stereo sets, thanks to 3 meter (9 foot) cables.

Crazy, Bob, anger management course, wow, I'm getting wound up just imagining being told to go on one, let alone actually going, hehe.
I've done a few little courses recently and all end with being asked to fill in a feedback form (actually feedback forms are everywhere these days). I no long fill them in on "principle" that being I only consider negative feedback as having any value to improve things, but found it wasn't taken that way and was usually ignored entirely, taken as "trouble making".

A faraday cage doesn't need to be grounded, unless maybe if you include capacitively?
The acquired signal has to go someplace. If not to ground it could re-radiate into the interior of the cage nullifying its effect.
Because you risk creating yet another accidental antenna. Which was the problem that lead my friend to call on my services, resulting in a very expensive pile of cables taken out of his gear.
The only way to be sure it will work correctly is to go the microphone cable route and ground the shield at both ends.
I'm prepared to bet you that if those cables had been wired correctly, twisted pair carrying signal flow and return and shield connected at source end only there would have been no problem.
@scottjoplin ... can't say. That all happened over a year ago and I don't know what became of the cables. You might be right...
BUT, don't miss the point here...
That doesn't mean my friend was not ripped off.
Seriously almost $7,000 in cables... NFW, my friend.
That is simply ludicrous no matter how you slice it.
You appear to be thinking I'm angry because the cables were a problem and that's not the case. For me it was a pretty routine service call. But you can bet I was plenty p**sed when I saw how much he paid for them.

I think you should read my thread and the links, some of them are very long and detailed, things are not always as straight forward as you seem to think. Your friend was ripped off, no doubt about that I'm afraid.
