I'm using the built in video player, and have tried on several different skins, but I used to be able to cycle through all the different aspect ratios for videos using the (appropriately enough) zoom button, but it doesn't do anything anymore. I might have inadvertently changed something, and can't figure out what. Anyone have any ideas??

And I do have Enable zoom checked. If I remove the check, I see the "Full" at the top corner as if I were cycling, but still can't. If it's checked, no cycling, no words.
