@truth Unknown: It took me a minute after reading your post to realize this wasn't the "black bar" thread anymore. "Cropping of the input"...? Where is there an option for that? I assume you're not talking about a pSX option, but I'm pretty sure I don't have that option *anyplace* computer or TV related. I swear I feel like I'm missing a joke here... Sorry but the black bar complaint threads are getting on my nerves. Well, when I made that statement, ATI was not the only company on my mind. Since I don't really expect everybody to love ATI as much as us, I had every company in mind, based on what I've seen, looking at Best Buy and online inventories in general, it always seemed like the higher-end cards were more likely to have the capabilities. I'm just glad my 9250 has video-out (both S-Video and the yellow A/V video (wish I knew the technical name for those R/W/Y cords)). I believe those cables are called composite, or thats what the video signal is called.

I thought they were called composite cables, but then I got yelled at by someone at Radio Shack for calling it that. I still call them that sometimes though... lol.

Red, white and yellow leads are usually right channel audio, left channel audio and composite video, respectively. Well, I guess, strictly speaking, it would be incorrect (or inaccurate. It is actually a kind of composite, I suppose) to refer to the whole bundle as a composite cable; only the yellow lead is actually composite video.
But don't confuse them with component video which, although also 3 leads, is separated red, green and blue signals, each in their own lead - therefore also referred to as RGB. No audio signals included there.

Component I do know. Component cables is what I use for my PS2.
I guess you'd have to call them RCA/Composite cables, or something like that, if we get down to what they actually are. But you see, my PS2 cables are called component cables by every company that makes them, and only the video cables are component (the audio being RCA, just like the other cables). So if they can call that whole setup "component", then I guess we'd just be following the standard that *they* have set by called the other setup "composite". So I think I will stick to that name, and if any bastards at Radio Shack tried telling me I'm wrong, I'll give the same reasoning I just gave here.

Well, strictly speaking 'composite' and 'component' should only refer to the video cables, I guess, or you're going to get confusion.
Maybe we should use the most widely used term - 'audio/visual' cable. Or, if you want to be more specific, 'audio/component video' or 'audio/composite video?'

Normally I'd suggest calling them the most accurate and simple things of all:
"Composite A/V cable" and "Component A/V cable".
You'll note the use of "cable" instead of cables-- that's because when you're talking about a console, everything goes into one jack on the console end. Semantics to make it simpler.

Well, I've rebuilt my Playstation 'composite A/V cable(s)' so that the three leads (one composite video, left audio and right audio) are three distinct cables - only joined at the Playstation end.
So is that a cable or cables?
Could just call it a 'composite A/V connector,' I suppose... or 'composite V/A connector...?' ;D

I'd still say cable, since the most important end is on the PSX side, but your mileage may vary. Or you could just call it "component cabling".

Sony calls it a "Component A/V Cable", so that's what we're going with. No more worries or arguments... Sony makes the console being emulated here, and so we'll go with their naming standard for their own console. And "composite A/V cable" will be the name for the other type. So that's that. Have a good day.

And we all know Sony is the very definition of the word "trustworthy..."

Whilst semantics are fun, can I ask the techies a relevant question -- does the PS1 actually output anything beyond composite video? DScaler can hide a multitude of sins, but I'd rather have native RGB or S-VHS...
Asking because I've basically given up trying to get *anything* from Psygnosis to run, on any emulator, ever.

in early model versions - yes.... Well, mine is a SCPH5502. I've tried forcing RGB thru my existing cheap-nasty-indonesian SCART, to the TV, and seem to be missing the entire red channel! Will have to see if all the right wires are connected... Some extended googling did turn up this though, which might be useful with a little modification, for getting a quality video in feed to the computer. Since RGB input to computer is prohibitively expensive, RGB -> S-VHS conversion is a better option, with most video in solutions capable of taking it. Has anyone tried this kind of thing before? Presumably, this would also work for a PS2 down the line.

You need to be carefull when you select a tuner (or VIVO) card because of MPEG. Some cards like the Hauppauge WinTV-PVR-150 require that the signal be converted to MPEG before it leaves the card. You could decompress the signal but the damage has already been done. For those who are not familiar with MPEG, it requires several frames of video to make its calculations and thus can NOT output real time video. There is a small lag and while it can be small (less than a second), it makes playing games through the card all but impossible. In case anyone cares, this is why robots can not use MPEG for real time vision. I made the mistake a month or so ago (I did not realize that the card only outputed MPEG since it is rarely ever put in the specs) and had to return it. Because of this, you may be better off getting a cheap card because they tend to not have the MPEG compression hardware on them. They use software to do the compression and thus you can capture a "pure" signal.

The Hauppauge WinTV-PVR-150 seems to be very much around using your PC as a digital video recorder, ripper713, so if you're watching using its 'pause' facility, then, yes, you're watching an mpeg being recorded on your hard drive and played back - there will be a delay.
However, I very much doubt that it's not possible to to view input video or TV directly over the PCI bus, without being converted to an MPEG format, and this would result in there being no effective delay.
Obviously, the process of viewing video by recording it in any format, not just MPEG, and playing it back is going to result in a delay, and so would not be appropriate for "real time vision."
