Why is it when a stereo has a bass adjustment it is called "Double Bass Bosting with cherries on top".............. It's merely a marketing gimick. So people who don't know go. "Oh look i have to have this TV cause it's dvd ready and the others arent" Unfortunately Mike you have been sucked in by the seven salespeople you saw. They said that YUV is far superior to the others so that you would by a more expensive tv. The reality is is that yes it is superior but not by far. if you were to do a rating as to the quality of the different connection types, it would go a bit like this 10 SCART 9 YUV 8 S-video 6 Composite (RGB,RCA) 3.5 RF THe biggest thing to note though is if you are using your s-video cable or YUV cable that came with your dvd player or tv, then the quality is probably only as good as a really good composite. If you want proper YUV or s-vdeo, you have to spend some pretty bucks on a high quality cord.	roofus (483)
78010	2002-09-11 03:21:00	Okay, I decided to do a bit of research, and from what I can find on the net, what the salespeople told me was correct, but not 100%. YUV Component is not the best, but it is very good. But it is still a lot better than the others. Here's a snippet from dansdata.com (I found several other sites that said pretty much the same thing, but I used this one as I've heard of dansdata before :)) In colour difference component video, the first channel is luminance. Notated Y, the standard abbreviation for intensity, the luminance is the signal’s brightness information with no colour data. Y by itself gives a black and white picture. The other two channels are called colour difference signals – they’re notated R-Y and B-Y, and are the difference between red and the luminance and the difference between blue and the luminance, respectively. The colour difference channels can be algebraically recombined with the luminance to give a full colour picture, without having to transmit the green data that, on most video, takes up more bandwidth than the other two colours put together (on average, green is 59% of a video signal). Prosumer Y/C video is sorta-kinda component, with two channels, but is never referred to as component video, for two reasons. One, everyone knows what component video is and letting $3000 camcorders into the club would cause confusion. And two, all Y/C does is extend the separate chrominance and luminance signals that most low-end video formats already encode into the cable connections. Every VHS VCR records video as separate luminance and chrominance; SVHS and Hi-8 ones with Y/C output can send and receive this two-channel video without squishing it into composite. Y/C (S-video) is better than composite, but still much worse than component. The chrominance signal Y/C uses is PAL or NTSC-modulated, ready for integration into a composite or RF modulated signal in the appropriate format. This makes Y/C video inherently PAL or NTSC, while real component video is format-agnostic – it can be encoded into any format you like. Y/C, or S-Video as it’s also known, is used only be SVHS, Hi8 and ¾" SP equipment. (emphasis added) I'm not too worried whether the salespeople lied or not - the tv I bought I would have bought whether it had it or not; it wasn't the deciding factor. But I like to believe that they weren't lying about it. Mike. PS If I'm wrong, feel free to tell me, as I would like to learn more about this sorta stuff.	Mike (15)
78011	2002-09-11 05:11:00	Just to let you know that I have tried my DVD player on component video and s-video outputs and could not see any difference at all. It may have something to with the TV being a rear-projection TV?? The picture is not as clear as say a 29" TV anyway. So I have stuck with s-video cable mainly because it's only one cable not 3! The less spagetti the better!	CYaBro (73)
78012	2002-09-11 07:31:00	What you have cut and pasted is correct, however i do refute their claim that it is considerably better, although as already stated we do know its better. If you would like to know the ins and outs of dvds check out DVDdemystified (dvddemystified.com) Where i learnt my info on the components and also from other research i did can be found in section 3.2	roofus (483)
78013	2002-09-11 09:19:00	Thank you for the continued helpful advice. Unfortunately that page won't open for me at the moment, roofus, so I can't have a look. In our Philips TV manual we have: Connections: Monitor Out: 1 x S-Video, 1 x Video, 2 x Audio Sockets Video 1: 1 x S-Video, 1 x Video, 2 x Audio Sockets Video 2: 1 x S-Video, 1 x Video, 2 x Audio Sockets The audio output is 2 x 12 W RMS if that has any significance. I see that it is S-Video compatible, but I've no idea whether it's Component compatible. I would say probably not as the TV is a 1995 vintage. Hopefully our choice of DVD player won't be too limited with these specifications and that the salespeople know their stuff when I ask them. I don't particularly like it when they try and sell something more expensive that you actually need and you're too ignorant to know. One thing I'm wondering and am quite embarrassed to ask, is how do you hear the music CDs that you can play on them? Does the TV have to be running in order to use its speakers, or do you need to hook the DVD player up to a stereo? I've seen nothing yet that explains this.	Susan B (19)
78014	2002-09-11 11:03:00	Hi Susan Sorry, but you either listen through your TV or patch it through to your stereo. The TV is not a viable option for quality sound unless tyou have a home theatre system, and I ask myself, when would you ever get achance to watch TV unless it was by reflection from your computer screen!
