I don't think so. If it was over scanning you'd be loosing the bottom part of every broadcast and most probably not seeing logos. I'm seeing the same thing. Missing line 7.
Edit of above. I was looking at my TV2 output when I made the above comment. On my TV1 output I'm seeing the full seven lines and am missing a little bit of line 7 on TV2.
Also, what is the most current software for the 211 and when was it spooled out.
Another argument for it not being the TV is that it only started with the latest update. Glad that others are seeing the same thing.
Since some people see it and some don't, my guess is that it's an interaction between something in the update and certain TVs. Mine is 1080i (won't do 1080p). Is that true for others who see the problem?
