Problem still existed where I could see all the menu's just no picture. So I went in to the H20 and performed a system reset(Reboot). After this everything seems to be working just fine. The H20 outputs to the Anthem at 480i, and the Anthem outputs at 1080i just fine.
My AVM50 came with 1.11 installed from the factory.
Darell, that's fine if you are watching an SDTV channel since they are all 480i anyway, but if you are watching an HDTV channel you want the H20 to send 720p or 1080i to the Anthem (according to what's coming in on the channel at the moment). If you force the H20 to use *ONLY* 480i output then you are forcing it to downscale all your HDTV to SDTV resolution before it sends it over to the Anthem.
I don't have an H20 myself, but my understanding is that the way it is supposed to work is that you set it to "native" to track the resolution of the incoming TV channel (instead of using only one, fixed, output resolution), and then you ALSO set the resolutions your TV can support.
So you should have "native" set along with 480i, 480p, 720p, and 1080i since the Anthem accepts all of those.
Then the H20 will use the correct resolution according to each station you switch to.
The problem people are reporting is that when the H20 tries to use 1080i -- i.e., when you have tuned to an HDTV station that is currently broadcasting in 1080i -- the Anthem produces a scrambled picture and, what's worse, OTHER source devices stop working properly through the Anthem.
The workaround people have found -- until Anthem fixes this -- is to turn off 1080i as an option for the H20's set of "native" resolutions. Leave 480i, 480p and 720p. Then the H20 will use 480i for SDTV channels and 720p for all HDTV channels regardless of whether or not they are currently broadcasting in 1080i.
And this also, apparently, fixes the problem folks are having with OTHER source devices. I.e., you only have to do this fix with your satellite or cable TV box.
So here's the test: Set the H20 to have all 4 resolutions active in "native" mode. Tune to an HDTV channel that's broadcasting in 1080i, and see if you get a good image. If so, press Select on the Anthem remote twice to get it to display the incoming resolution. Verify that it is 1920 x 1080i /59.94Hz. There will likely also be a "CP" at the end of that line indicating copy protection is active.
If you DON'T get a good image, then try the workaround of disabling just 1080i from the set of H20 resolutions. Leave 480i, 480p and 720p as well as "native" mode. Try your 1080i HDTV station again. It is likely that it will work but the Anthem will now report that it is receiving 720p instead of 1080i from the H20.
Please report back whether 1080i input is working properly for you or whether you had to do this workaround of limiting things to 720p.
