I know that you can get the colored HD plugs for an HD player/Xbox etc.... Is there really a signifigant difference between those and an HDMI cord? If so why do they rate those cords as HD?

Depends on the quality of the cable. Theoretically, there is a difference. When using component cables, there is an digital to analog conversion that has to be done. With HDMI, there is no conversion, as it can accept a digital signal.
If you have a nice setup, you should see a difference.

Ok they say that you can't get HD using Coaxial. Yet all the cords coming out of my wall from my directv dish are coaxial. When I had a Directv HD reciever I was getting HD. How is that possible when the signal comes into the house via coax cord?
Shouldnt that cord be some type of HDMI?

Ok, this was in the movies forum, so I assumed that we were talking about HDDVD, and not HDTV.
The coax feed that comes from the satellite, to the wall, and to the DTV box is coax. However, the connection from the satellite box, to your TV, does not have to be coax, and shouldn't be. To get the best possible picture from the box, you will want to use HDMI from the DTV box, to your TV. Then next best option is component.
If you are bringing coax back to your TV, you are not getting HD, because the coax connections on most TVs have a maximum resolution of 480i (standard TV).
Did I confuse you?

No not confused. But what I dont understand is if Coax is only capable of putting out 480i how the hell does everything coming from the wall(coax) into the box get back up to real HD if its inly coming in at 480i? Does the box upconvert everything back?

pretty good.
Its not the coax itself that is incapable of outputting more than 480i, it is the coax connection on your TV. Your box will do some coversions. My Cox HD box, will only allow one resolution output per connection. That is, I have to choose 1080i as the default resolution the box will send to my TV. The HD box can accept all kinds of resolutions, but only send out whatever resolution you set as the default on the box. (I know it is starting to get confusing now)
Your TV will most likely do some added conversions as well, but we don't really have to get into that.

Shane's question is easy to understand, hard to answer.
1. Signal comes from a coaxial cable from wall to his cable box at 480i.
2. From cable box it is sent out at 1080i/p to his TV
3. How is the signal coming in at 480 off coax and changing? How does it go from analog to digital?

So, DCR's answer is
The Coax sends at 1080i/p. The box sends it digitally at the same format. However, the coax on a TV can't take that, only 480i. So, it would be DOWNconverted to play through coax.
There is no upconversion.

Right. I think of it as coax from wall to 480 coax TV is a fat, ugly signal.
Coax from the wall to an HD receiver is digital, lean and mean 1080.

If you use the HDMI what about the sound? I used component so I could have the digital audio as well, is this not right?

That's pretty much it, in a nutshell. HDTV's highest available resolution is 1080i, and will be for at least the next few years.

Yes and no. Component carries no sound, but unless you are connect it to a receiver that allows HDMI video and audio passthrough, (only the most recent do) in order to get Dolby Digital or higher sound from your DTV box, you will probably have to connect it using digital audio cable(coaxial or optical) . My Cox box is currently connected with 3 connections. One S-Video connection for my standard def watching. One HDMI cable for HDTV watching, and one optical cable for all sound for both.
*Shane do not confuse coaxial audio cable, with coax video cable.

Donald playing translator is KING! Thanks everyone for explaining it. Thanks Donald for making it into english.

Actually I didn't read that correctly. The feed coming from the wall is coming in at 1080i/720p whatever that particular channel or show is broadcasting, not 480i. There isn't a conversion done by the DTV/Cable box just to aquire the signal. The box just "knows what to do" when it gets higher than a 480i signal. Without that box, you just see a 480i connection. Before it can send the signal out to your TV, there may be coversion done.
Yes, that is the answer, but I was translating his question. That's what he was asking and assuming.
