Two days ago I watched the Space shuttle Endeavour launch and the picture quality was the best I had ever seen in HD! :eek: I mean even at 2 feet from the screen I did not see any pixels or graininess whatsoever, but tonight I notice graininess or pixelazation at 8 feet from my LCD HDTV! I can only imagine what a Blu-Ray player (1080p) can look like! I'm new to HD and am at a loss as to why some programming is gorgeous and some are just done cheap. :confused: Is there a standard for HD content or what?

There is no standard so to speak. Quality largely depends on the original source material (how it was filmed, what codec was used, etc.) and how much compression is used by Dish when sending it to your receiver. I have noticed the same. HDnet (3 channels) Discovery channel and a few others usually give the best HD imagery while channels like TNT, SyFy, Comedy Channel and many others are sometimes just OK and other times quite poor. With the latter stations mentioned, it's all about the advertising money and to hell with quality.

I have also found that HD via OTA is better than anything Dish or any other provider sends as OTA is compressed less.

Agree with all of the above! :yippee:

In my case, my TV happens to be a native 1080i, so I have also noticed a difference in over the air broadcast quality depending on what their native broadcast method is. CBS is 1080i, whereas FOX is 720p for example.

I know that when viewing through the DISH receiver, it is converted to whatever you choose in the setup menu I believe.

What is HD via OTA? :confused:

Digital High Definition Over The Air, buy an antenna vs cable or satellite.

What HD antenna would you recommed for an apartment? Will I still get 5.1 Dolby Digital?

Yes you will get DD 5.1 as for an antenna I would recommend going to a site like TV Fool put in your address and zip code and it will give some recommendations. You will be limited though since you are in an apt. building.

I did the analysis and it says an indoor HD antenna will do the job, but just to be sure I would like to put the antenna outside 6ft above the ground. Only thing is which antenna would be better, I have never seen an HD antenna before. Any recommendations? Something low profile maybe...

An antenna is an antenna. HD doesn't enter the equation, FYI.

From what you say, I'm sure something like a Channel Master 4221 or an Antennas Direct DB4 (which are outdoor antennas) would work just fine.

First. do you have any VHF signals to contend with, that might alter the antenna selection.

If none the above should work and they might even be OK with VHF, I get good VHF on my RS U75-R 6 miles from the transmitter on channel 11.
