    Tonight I am noticing aliasing(stairstepping) in the channel logo and any text superimposed on the screen on Animal Planet HD. I am also noticing it in some of the actual video, doesn't seem as sharp or clear as it usually is. Using a ViP722 dvr, television is a Panasonic 65VT60 plasma. I have not changed any settings on anything in my setup. I have not noticed the issue on any other channels.

    Are you sure you are not zoomed in? Try the "*" button on the remote to see if you are accidentally in one of the zoom modes.

    Nope, was not zoomed, all the logos/banners were visible. I am going to check it out again tonight and check more channels. Thanks for responding, I will check and make sure that someone didn't change something on the TV.

    I wasn't watching at the time you were... but I did check the channel a couple of times later and I didn't see any problems like you were describing. IF it was a problem with a particular show (maybe they are still airing some upconverted SD content) then I might have missed seeing it for that reason.

    I know some of those channels (Animal Planet, History, TLC, etc.) were airing zoomed SD content when they first launched that looked weird in the ways you were describing but I don't watch any of them regularly enough to know if they still air any of that content.

    Checked my audio reciever and the video conversion is turned off there so that is not the issue. No changes to the settings on the TV have been changed, and the aliasing is not on every channel. Tried changing the ViP 722 to output 720p rather than 1080i as it was originally set and while that did lessen the aliasing it also softened the picture and generally made it look worse. It appears to be Discovery Network channels that exhibit the aliasing on my system as I noticed the same issue tonight on Discovery watching Street Outlaws, and Animal Planet is still doing it. IFC does not exhibit this issue and looks spectacular, the Blockbuster channels look awesome also so I have decided that the issue is with the channels and not my equipment. Not sure what they have going on but it doesn't look good.

    Great...
    olds:
    I've seen that terminology before [ video card program on my computer] for us less than knowledgeable, what does it actually look like on the screen? [aliasing].

    Animal Planet is a 1080i channel. Dish Network's use of "HD-Lite" for every single 1080i channel might be playing a part in the issue.

    The problem is not being seen on "every single 1080i channel". The thread starter has stated "I have not noticed the issue on any other channels" more than once.

    Hence the use of the word, "might." Hopefully it's an issue they rectify prior to going headlong into 4K.

    At the moment there is nothing to indicate a Dish problem. We don't truly know if it is an Animal Planet problem OR specific content on Animal Planet. Some of us have viewed other content on that channel at different times from the thread starter and not seen the issue... so nobody has yet been able to replicate his problem in order to truly know what is going on... so speculation on random things you may not like about Dish isn't actually helpful. Also 4K has nothing to do with this topic at all.

    Great...
    Can anyone describe "aliasing" so those of us that are not video geeks could understand?

    The main issue I am seeing is on channel bug logos and on wording that is part of the actual channel (not overlayed by the reciever) has stair stepped edges. When watching Street Outlaws on Discovery HD last night The "D" logo on the bottom right did not have smooth curves on its edges, also the top and bottom of the logo had fine horizontal lines in them. I didn't notice it right away in the actual content, you had to look at it a little while and I started to notice the same thing in logos within the content (T-shirts that people on the show were wearing exhibited it) and after looking closely the actual content looks slightly soft.

    I saw the same issues watching Finding Bigfoot on Sunday evening on Animal Planet HD (a Discovery Network channel). Right now I am watching Curse of Oak Island on History Channel HD and it looks great, logos are sharp and clear, no stair stepped curves or horizontal lines. As I stated, IFC looked fantastic and the blockbuster channels (Sony Movies, Epix 1, 2, 3, etc...) look fantastic also so the problem is not with the TV or DVR. For all I know the problem may be with the signal that is being fed to Dish. I am assuming the problem is with the Discovery Network channels as I have only seen the problem on their channels.

    I do sometimes see issues with the channel logo overlays... so I may have seen what you are talking about. It's hard to say if it is a Dish compression issue for those channels OR the way they are delivered to Dish OR frankly, the design of the logos themselves. Sometimes channels aren't using the smartest or highest-quality logos frankly.

    I don't watch these particular channels often enough to say if it is a regular thing or a fluke thing with certain programs. I at least see what you are talking about with the channel logos not being as smooth as they ought to be... at least I think I'm seeing what you are describing.

    At first I thought it was just the logos themselves, but then noticed it on lettering such as the credits on the same programs. I also noticed it on logos within the program content itself, like T-shirt logos on people in the program or road signs and diagonal lines within the program so it can't just be that they are using crappy logos to overlay the programming. It is very visible on the Animal Planet logo on the top right of the screen. The green sideways "M" looks horrible, what should be smooth diagonals, look like zigzag lines.

    I'll have to pay some more attention and actually watch something on some of these channels a bit longer and see. When I was test-watching I wasn't seeing any other on screen text that jumped out at me as flawed in the way the logos seemed to be.

    Yeah, after watching a program for a little while you start to notice that it doesn't look quite as "HD" as it should. I also noticed it in material where you would ordinarily see detail, like foliage. It may be some sort of compression going on.

    Somebody fixed something on Discovery, it is looking much, much better. Actual HD now.

    Maybe it was a problem on their end, with the feed they supply to Dish. It wouldn't be the first time.
