My problem with HTML5 is you can't jump around in the video reliably. Lets say it's a 5 minute vid, you're 2 minutes in and "whoa, what was that?", try to go back 10 seconds and you get the loading screen. Or you're 2 minutes in, bored, jump ahead a minute, and get the loading screen. Or 2 minutes in, someone knocks on your door, you pause, open it a few minutes later and get the loading screen.
doesn't help HTML5 seems to load at the speed of play. Forget about watching the first minute, getting bored, and jumping ahead 2 minutes.
And I can't seem to stop the auto-play videos no matter what web-sites google sends me to nor which settings I set. Autoplay video? Close the tab. Don't care what the content was, autoplay video is an automatic close the tab.
Oh yeah. Win10, fully patched, Chrome, latest version.
