Note that the lines would only present if I entered the menu several times or spent quite a bit of time in the menu. I found that I had to turn off AVM and turn back on to get rid of the horizontal lines. Additionally, s-video sources would show white broken horizontal lines on a light grey background at the top of the screen approximately 20 pixels (or more) thick. The vertical hold on s-video would shift from two broken lines visible to one line visible then back again.
Anthem support suggested upgrading to 1.33 fw and since then I have not been able to reproduce the horizontal lines in menu. However, the two vertical broken lines are still at the top of the screen when viewing s-video sources. I am going to call Anthem and let them know that 1.33 firmware has not yet completely fixed my problem.
BTW, I have the red video card and, other than this one (fingers crossed) problem, I am very pleased with my HD30.
I just remembered that my wife notified me that the horizontal lines appeared while watching DTV prior to the 1.33 fw upgrade and did so with normal viewing without entering the menus.
Horizontal lines in the body of the image are definitely a sign of trouble. Getting to the latest firmware is a good first step, but if those lines are still there you need to get serious about isolating where they are coming from.
The first question should be, do you still get them if you use the Anthem's internally generated test patterns (Video Source Adjust / Patterns)? Those patterns are independent of any source video device. If you do, then the next step is to disconnect everything from your system except for the power to the Anthem and the TV and the connection between the Anthem and the TV. That's it. No audio connections for example. There should be nothing else connected to the TV either. Then see if the problem still exists. If so then you can be pretty certain it is a hardware issue in the Anthem. If NOT then you reconnect things one at a time until the interference reappears.
When discussing this with Anthem you will need to describe precisely what you are seeing since there are particular sources of interference which each have their own tell-tale patterns. For example, if the horizontal interference appears to be moving slowly up the screen at a constant rate then that's a sign of 60Hz power line interference. When you talk to Anthem expect to answer some questions about what the interference looks like.
You could have a hardware problem or you could have some sort of external interference which is getting into your video. The single most common source of garbage getting into people's systems is interference that comes in along the shield part of their cable or satellite TV feed. So whenever you have a problem like this one common step is to temporarily disconnect the feed wire between the wall and your cable or satellite receiver to see if the problem goes away. If so there are solutions. Interference of this type travels between boxes in your system along the shields of the cables connecting them, so it is often difficult to isolate which box is generating the problem unless you go about it in a logical manner -- disconnecting and isolating portions of your system. But if disconnecting the cable/satellite feed eliminates the interference then you know you've got it nailed.
The lines at the top of your S-video sources could be something else entirely. A typical video setup with the Anthem will cause your display to show every last pixel, right out to each of the 4 edges. Usually this is good. But some sources produce garbage on the edges of the signal simply because they expect you to be using a less perfect video setup that conceals the true edges of the image off screen -- called "overscan".
For example, Closed Captioning information often appears in the top few rows of the image. And local stations that rebroadcast national feeds sometimes offset the image horizontally by a few pixels leading to garbage on one edge or the other.
This sort of problem is in the content. It is not a failure of your stuff.
The Anthem offers an easy way to deal with this. In Video Source Adjust / Crop Input for that source turn Edges ON and select a number of pixels. A strip that many pixels wide will be cropped out all the way around the image.
