Native HD can mean two different things.
First, it may refer to the resolution. Native HD resolution is either 1080 line or 720 line, depending on the format chosen for the production. Many televisions have a different line count in their displays so the image needs to be re-sized to fit the resolution of the screen. The image is no longer in its native resolution.
Second, it might refer to the signal bandwidth. Production HD uses an uncompressed signal with a data rate of 1.483 Gb/s (that's 1,483,000,000 bits every second). That is the native data rate. By the time the signal is delivered to homes, it has been compressed to as little and 5Mb per second (5,000,000 bits per second).
The data rates refer to 720p and 1080i signals. 1080p signals have a native data rate of 2.966Gb/s
Yes, however it won't be stored in native DVD format.
Currently the highest resolution available for a HD Data Projector is 1600 x 1200 pixels. This is a very high definition and very few applications support that as a native resolution.

720p is one of the HD formats so it will display HD quality. Although most Bluray content is generated as a 1080 signal, some is produced as 720p. Either will work on any HD television although using a television with a native 1080 line display will deliver the best resolution available for any current HD content.
Yes they can. They will operate on any HD television although a television with a native resolution of 1080 lines will provide a higher quality image for any Bluray disc that uses 1080 content.
All HD televisions are capable of displaying both 1080i and 720p formats. They are both considered to be minimum standards for HD capability. 1080p is a higher data rate than the others and a few older HD models cannot handle the format. Any of the later HD televisions will also accept 1080p. In all cases, the television will convert the incoming signal to a size to suit the native resolution of the television.
"HD ready " says that the television can display an image from an HD signal, whether it is a 1080 or 720 line format. However, it makes no claims about the resolution of the screen itself. Some HD ready screens are as low as 480 line which is the number of lines in an NTSC (North American format) standard definition signal. The image quality will therefore be no better than SD even with an HD signal being delivered to it. "Full HD" is less well defined. It normally means that the display has 1080 lines and it can show a 1080i image at its native resolution. Some people will say that full HD must allow 1080p signals to be shown at the native resolution and frame rate. Full HD can also mean that the screen is a 720 line display, or higher. As 720 line is a recognized HD format, a display that boasts 768 lines can legitimately be called full HD. The only way to establish the type of display is to check the detailed specification. Ideally, the display will have a native resolution of 1920 x 1080 pixels and will handle 720p, 1080i and 1080p signals. Any other resolution will demand that the incoming image is resized from 1080 to some other format, so losing quality against the incoming 1080 signal. The final check for a television is a visual one. Disregard all the specifications and watch the television while it shows the program material that you are likely to be watching. If the display looks good, then it's a good television. That's very subjective but the buyer is normally the person who will be watching it.
The dish box needs to be a HD box to receive the HD stations in HD.
The highest HD resolution is 1080p (or 1080 pixels) and in order to get the best HD from the Blu-Ray disc, the TV's resolution should be 1080p as well. A lower native resolution television will reduce the effective resolution.
The difference between HD ready and full HD is fairly subtle. To display standard definition signals, there will be little difference between any model of HD television but the difference is described here... Normal HD resolution uses 1080 lines to build the complete picture. Most HD signals are broadcast in that format (the alternative is 720 line but it rarely used). A full HD television should have a native screen resolution of 1080 lines and will be advertised as 1080i or 1080p native resolution. By contrast, other HD ready televisions may not use 1080 lines for the display and the incoming signal will be processed and resized to fit the lower resolution. Typical line counts are 768 or 900. The end result is still good quality but the effective resolution is reduced to the number of lines on the display. Freeview (The British digital terrestrial television service) is currently broadcasting in standard definition only. Therefore, with a line count of 576, the native display resolution will be higher on any HD ready or full HD television. The resolution of the image is NOT increased by displaying it on a higher resolution screen. However, Freeview is planning to begin HD broadcasting during 2010. Current Freeview receivers will not be compatible and will need to eb replaced with HD compliant receivers. Likewise, British televisions do not currently have HD Freeview receivers built in. No doubt they will incorporate HD Freeview during 2010. If the television is to be used for HD Freeview in the future it may be worth looking at 1080 line displays as they are potentially the best image quality. Before buying any television, it is worth looking at them first. Regardless of the specification, some look better than others. As we tend to spend many hours looking at our purchase, it is only sensible to make sure it is the picture that we like best.
Yes, but then the T.V has to be 'Full HD'.
Yes. The resolution of HD ready is smaller than Full HD. HD ready is not capable of 1080p resolution and Full HD is.
