I have the same issue, I was surprised to see it running at all on a SD 4:3 TV, but the overscan is clear, even the wife noticed it.1) I have a SD 4:3 tv (I know cave man) HULU programing comes in out of aspect for my TV and it just squeezes it down to 4:3 so the people look skinny. That would be ok for me but not what I want in my TV programming. Netflix etc. all seem to be just fine in this regard. The zoom doesn't work with HULU so when I change it to panel it still goes full and squeezes everything. My ROKU version of Hulu does not have this problem.
