Is there a difference between the quality between the 720p and 1080p videos? So far I've only been able to test with youtube content and the quality looks the same on my 55LW5600, 55inch LCD TV.

The 1080p sets are the only sets that will display both broadcast formats of 720p and 1080i with no loss of detail. They upconvert (scale) the 720p to 1080p (screen resolution) and deinterlace the 1080i/60 and display 1080p/30 with no detail loss.The independent experts all tend to agree on this point.. 1080p is just about the least important factor in picture quality particularly if you are seated outside the physical boundaries where our human eye can no longer discern the resolution differences. This is a sliding distance scale which depends on screen size in relation to seating distance. Here's one such chart example:
http://hdguru.com/wp-content/uploads...ance_chart.pdf
Color accuracy, contrast, black levels, scaling/processing all come before resolution in importance. The smaller the panel, the less important resolution becomes UNLESS you will be using the panel as a computer monitor (where you'll often be seated within 4ft. of the display, and at a distance that close, you will much more likely notice & appreciate the difference). On a 37" panel, for example, you have to be within 5ft. to tell the difference. And that's under ideal circumstances.
Disregard any poster who suggests otherwise. They are seeing something other than the true difference between 1080p & 720p when they claim they can tell the difference even on smaller (37"-42") panels beyond 5-6ft. The difference they claim to see is likely to be in the processing of non-native signal, i.e., panels will typically display their native rate better than they can a lesser resolution which the panel then has to scale to match it's own.
If you have a 1080p 42" panel, for example, assuming for a moment that you are seated outside the optimal seating boundary for fully resolving (seeing) 1080p content, the panel will still often look better displaying 1080p content merely because it doesn't have to scale the resolution. Feed the 1080p panel some other lesser resolution which then must be upscaled to match the panels 1080p native rate, then on all but the most expensive panels with excellent processing, the image will look inferior not because 720p is a lesser resolution, but because the panel simply cannot do a very good job scaling it. Or, maybe the panel handles scaling these duties well, but the particular 1080p model just so happens to have better color rendition, contrast, etc., than another particular example of a 720p panel, and as a result, it looks better under any circumstances, regardless of their comparative resolution capabilities.
Bitrate matters. 1080p with low bitrate can be worse than 720p with high bitrate.
However, what also matters is encoding efficiency which can't be explained simply. A damn good encoder can produce high quality video with minimal bitrate.
Given this statement above it sounds like you have experience with this process...
Do you recommend specific encoders for this task or have a defined process you follow to produce high quality videos?
Thanks in advance,

Yeah, most companies standard HD is only 720p anyway. So there really wouldn't be any difference between TVs if that is all you are watching...

ex: cbs, fox, espn, etc.
nothing if you are >10 ft away
depends on your distance:
Why the hell did you link that? I'm gonna have "chola" stuck in my head all night.
Someone told, that he can see very clearly HD TV - 47" LED-LCD Samsung from even an inch or 10 inches...
I've explained, that there's some certain distance of viewer from TV has to be....
Answer was: NO, I can see HD from an inch....well.....I stopped arguing....
Did you read the link above about native resolution of the TV, though, possibly being cause for people seeing differences they shouldn't be able to?I would say I can tell a difference at 14' between DVD 480p and Blueray 1080p on my 47". I have movies on both formats. Now I'm not sure how many other things are different between the 2 disks that could make it look better.
According to that chart I shouldn't be able to though.

I watch most of my movies at a range that 720 would work fine at according to that chart, but occasionally I will sit about 5' from the TV on the coffee table while gaming

I dunno, from about 8 ft. away in my BR, 720p looks damn sharp on my 32" set. I can't imagine 1080 looking much better. Now, when we ever get around to upgrading to HD in the LR, we'll probably go with a 55" display, in which case 1080p would seem a must (from about 10' away).
