1080p is only possible through source such as PC or HD-DVD/BlueRay.

If your PC can display 1080p but your TV can't accept it, then you got a crappy 1080p HDTV sets. (I have heard of some set that is capable of 1080p but for some reason they won't let you use the full 1080p for PC use. Pretty stupid/lame if you ask me)

also 1080p is only available through DVI/VGA/HDMI connections. Coax, Composite A/V, S-Video, and Component video cannot do 1080p

Coax, Composite A/V, S-video can only do 480i signal
Component can do 480i, 480p, 720p, 1080i

I don't understand this quote. Maybe I'm misunderstanding.

In Canada a lot of our TV infastructure is built around coaxial cable and don't use air signals like much of the U.S for HD. I work for a cable company that has had HDTV digital cable boxes for years now and can produce 720p and 1080i resolutions (IE. Motorla 5100,6200,6208,6412).

From my understanding the analogue information from the coax line is then decoded from the HD box and then displayed on your TV. HD is very bandwidth intensive, so I hear if you do try to stream a feed from your HD box to your PC using software, your hard drive fills up with raw HD data at a tremendous rate (I heard you need Windows Media center or something to decode the data).

So I'm not sure where the bandwidth limitation part comes in, in terms of not being about to do HD at all over coax cable / sattelite. I suppose we are kind of streched for bandwidth overall, and have to slowly get rid of analogue chs which take up too much bandwidth to begin with, but currently there is around 10 HD chs here (and not a bunch of duplicate feeds either like sattelite). I also know the fastest residential internet connection around here is 7 Mbps, which is not too shabby.
