Isn't 720p 1280x720?

It is true but the MAX resolution of a screen that can only do 1080i is still 1366x768 So in truth the Screen is not truly 1920 x 1080 because it doesnt support a resolution that high because the lines and dots are not actually there so think of it as virtually doing it and no offence to people but 720P looks a hell of alot better than 1080i because its the true resolution not some stupid way of displaying a non true resolution.....

^ Common naming misconception. 720p has a resolution of 1280x720, 1366x768 is actually 768p (yes, it does exist). Most 720p sets in fact support both 720p and 768p. 768p is however not a broadcast standard and there is some funky interpolation that takes place to make 720p content into 768p.

Anyway, you can read more about it here - http://hd1080i.blogspot.com/2006/12/...-problems.html

Wrong. 1080i is 1920x1080, no exceptions. However, most 720p sets are capable of displaying 1080i content through a process called scale down. This however results in poorer image quality. Content displayed in 1080i and 1080p is virtually indistinguishable from one another. 1080p is really mostly a gimmick aimed at luring in the consumer with some slight image improvements on some really high-end sets.

Just goes to show you how much people buying "true HDTV" in fact even know about what constitutes an "HDTV". Televisions carry obscure naming conventions that are quite meaningless, but have been put in place to supposedly make it easy for the consumer to know what they are buying. The naming for TV sets such as 720p, 1080i, 1080p can be simply interpreted as this:

(1) The number portion tells you the number of vertical scan lines (pixels). For example, 720p has 720 vertical pixels.
(2) The letter at the end, e.g., i or p, stand for interlaced or progressive. It is a method of drawing the image on the screen. See explanation here if you want http://en.wikipedia.org/wiki/Progressive_scan

Furthermore, if you want to know about how panels function, study computer monitors. "HDTV" sets are nothing but really large panel cheap quality computer screens.

Well yes, that's what I meant (and what I said, actually). And I'm in that group...I think DVRs are the single biggest transformational development for TVs in the last few decades, probably since VCRs were rolled out to the masses. But who cares if it's built in to the TV? Those same people who want their refridgerator to have internet access?

Yes, technically it does exist, but no broadcast supports it or streams in it so, ergo, 768p = 720p

Nope... if you receive 720p broadcast, that is what you get... not 768p (which is not even a standard)

1080i and 1080p are easily distinguishable by anyone with a discerning eye (at least on larger screens (42"+)).

The only standards that we should be concerning ourselves with are 720p and 1080p (and the forthcoming 1440p)

So true... which is one of MANY reasons why I will not have a TV in the house. My house. I own it. TV can **** right off ^_^

Sheer size doesn't determine picture quality. There's a host of other factors to account for.
some high end 17" laptops have 1920x1200 resolution but yeah, that doesn't matter if the /contrast sucks and it has a slow response time

Built in PVR might be nice, although that's why you buy an HTPC.

I have Directv and we pay an additional 20$ for HD service. HD-DVR is 10$ extra.

What I really think they should focus on is the upscaler on TV's. Most high end tv's like the 52" bravia in my living room has a great upscaler, but my 47" westy isn't as great, especially on some channels, they look like complete crap.

Holy crap, they're raping you blind! Time Warner is only charging me $8/month, and the HD-DVR is no additional charge! If they tried to charge me $30/month, I'd be buying a Tivo instead without looking back.
