[quote=What's in the beta firmware, by the way?[/QUOTE]
I'm not sure of what all is included, no notations were included. When I initially talked to Nick about the problem's I had with my first AVM, he mentioned that he could send me beta firmware for my replacment AVM. He didn't want me to install it on the original AVM in fear it may cause it to crash. He also wanted the people at Anthem to see the problems to figure out what may have happened.
A couple things I do see with the update...Video output (8) now has an OSD line for NTSC and PAL. Under the "picture" setting in the scaler menu, Video ADC replaces s-video. Included is s-video chroma TI level, s-video luma DNR level, video input gain and sampling phase. I wish I understood what these setting do.
I believe this also fixes the image shifting to the left. I no longer have this problem. However, I downloaded the update to the new AVM before using it, so I don't know If I would have had the problem with this unit anyway. Nick mentioned something to the extent of TV signals not following protocol with HDMI. Anthem had it programmed per specs, but this doesn't jive with the signal sent by the provider (they may not follow HDMI protocol) and this caused a shift issue with the AVM. Please don't quote me on the last few sentences, I'm going from memory and this is the information as I remember and I don't have a very good understanding of the technology so I could be a little off. I don't want to misrepresent nor misquote Nick as he is a wealth of information and very helpful.
If someone is interested, I could send the file (only good for the AVM 50!). Or if your more comfortable dealing with Anthem, just e-mail Nick at email@example.com
He usually responds within hours. Or simply wait until the end of the week, possibly next week and you can download it from Anthem's website.
