Oh, maybe I wasn't clear: I
do have the resizing issue when exiting fullscreen (not always, just sometimes). I was saying that there are other resizing issues
in addition to that.
I was using Chrome 16 to test the cache. For the HD stuff, I must say: I can't find many HD videos to try it on. HD videos are more likely to be supported by big corporate accounts, and they'll opt for ads in their videos, too, which means that the video won't be HTML5-compatible (that's the real distinction). If the video doesn't have Google Ads, then it can be played in HTML5. Otherwise, it has to be Flash.
