I do know what you're talking about! I imagine the web guru or someone more savvy than me will also post an answer, but I found I can "drag" the picture into the right focus. I click somewhere in the visible corner & drag with the right button. I do find that the enlarged screen will be somewhat grainy, though, so sometimes I go back-and-forth between the two.
When I try to watch a video full screen and follow your instructions to right-click and zoom in, I get only a partial screen (the bottom 1/4 or so)BethMI, which appears at the top of my screen.
