Christian -
I agree that this was certainly the wisdom of 20 or even 10 years ago. I question whether this is valid today. What specific evidence do you have that a TV rolling off an assembly line today does this? I am not asking this rhetorically as a way to say you are wrong. I am asking this question as a real question. Do you know or have you heard that a modern TV still does 90% cutoff? It would be interesting to test. Maybe I'll do it tomorrow. I have three brand new top quality big screen consumer LCD TVs. Maybe I'll create a PS document with successive 10% increments of "borders" and then send that image through HDMI from my computer to each screen and see how much is actually cut from each one.
I agree that many "smart" web repurposers run their video through a filter that does the automatic 10% crop to match the assumed 90% safe action from TV.
