I just got a nice home theater system (YAMAHA YHT-360) with the HTR-5835 and I am still confused about the types of cables. This is what I think I know: Composite Video: Can output around 640 by 480 or 480i S-Video: Can output 1024 by 768 Component Video: 480p, 720p, 1080i, 1080p HDMI Video: Same as Component, maybe a little better, it can also carry an audio signal like 5.1 Dolby Digital R & L: Stereo Sound 2.0 Coaxial: Can Carry 5.1 signal like Dolby Digital and DTS Optical: Same as Coaxial only less quality loss VGA: Up-to 2048 by 1560 or something analog signal DVI: Up to 1920 by 1200 digital signal I also got a Dell 2405fpw and I have watched a DVD on it via my PowerMac G5 and an optical Digital Connection. Would it be better to buy a DVD player with component out and watch DVD's on that? Right now via my computer the darks don't look too great, kinda green and pixelated. Do I just have to calibrate the color on my screen? I have an X800XT and I'm guessing that's good enough to watch a DVD. And will component be replaced by HDMI very soon? I wouldn't want to to be outdated right away. My component cable that I bought to plug my receiver to my monitor is an acoustics research cable and same with the optical one. Are they good quality compared to others? I haven't really gotten a chance to use them yet except with a 40 dollar Deawoo DVD player. The quality sucked, I hope it was the player and not the Cable. And many people here have said they use S-Video for Tivo and their DVD players. Since DVD's are only 720 by 480, with a DVD playing through S-Video look and different than Component? eventually My family also plans to upgrade to an HD Cable service soon and we have cox. I have some kind of Cable coming out of the wall here under my desk. It looks like a piece of s**t but I can get regular channels from it. Is that where I will eventually get HD channels from? I would plug in the HD receiver to my AV receiver via component and also a Digital Optical cable too. I presume that the Cox receivers have digital optical outputs in the back? And since my AV receiver doesn't have S-Video and my monitor does, I have this 2 year old switch box that I bought a walmart for like 40 bucks, or 20 I don't remember. I has S-Video, but I'm afraid that the quality will suck going through such a cheap box. My Science Teacher told me that gold plated cables are better conductors of electricity, so they produce better sound. Is this true? Will I even notice a huge difference? What is really the best company to buy cables from when you compare performance per dollar? The Audio cable I have is their Pro II Series and the Component Cables are their regular ones. So far everyone sounds good but I can still return them and get others. Is my PowerMac also giving me the best sound for my DVD's? My Optical Audio cable seems to be bent downward a little. Does this affect quality? I don't want it to brake. Ok, even more questions. My Home Theater System came with an unPowered Sub and I have been meaning to buy Powered one. Where can I find a good, yet cheap Sub. I was told by the guy at Best Buy that they start at around $200. I have a fairly small room about 12 by 10(yes small for a surround sound system) so I don't know what kinda power I need. My current sub isn't really what I wanted, I need more bass. The speaker cables that it came with are also not the best. They keep on braking(it's like 24 little tiny copperish wires that keep falling off) and I think I wont get as much power to the speaker as I wanted. So where can I get better wires that wont brake all the time? The receiver I got is also XM ready. Is it worth it? I love music but I hate 102.7 KISS FM cause of all the stupid rap. I like classic rock and cold-play and postal service type stuff. All I would need to do is buy the antenna and I'm ready plus the service. But I have been told that Sirus is better. What is? Is the quality really good? And when I get my Xbox 360 I want to use all this stuff with it. But I saw my friends cables that came with his and they seemed pretty cheesy. Would the Monster Cable ones be better? Now with all of these HD DVD players coming out I want one that will match my Black YAMAHA receiver. Which one would everyone recommend? Would getting the one that that will work with the 360 be more efficient? My receiver also only have 1 coaxial input and 2 optical. My computer's hooked up through one of the optical, then the 360 will be in the other. Does coaxial sound just as good if that were to be used for a future DVD player? Or should I just ditch watching DVD's on my computer and hook it up-to my receiver with a regular L & R cable? Even more questions. Will Dolby Digital 5.1 be outdated soon then be un supported in the near future? Or is it here to stay for at least a few more years? These are just some of the questions I needed to get off my chest. I know this seems like a lot, but I plan to use this for the next 10 years.
