My TV doesn't auto format, I have to do it manually: if a program is presented in a letter box format, I have to zoom; if it's presented in a pillar box format, I have to full, same with shows that are squished vertically; if they're squished horizontally... well, there's no fixing that.
But in situations like this, yes, just leave the shows alone, if we can adjust our TVs formats, we'll do it to suit our viewing experience, otherwise, JUST LEAVE THEM ALONE!
SEINFELD alone is one of the worst victims of this, that show looks completely different every few months.
