When using Windows 7N and embedded videos for YouTube and the like my users have been getting a black box. I tracked this down to when HTML5 is being used for rendering. Other than putting a bunch of sites in compatibility mode or installing the Windows Media Pack (which resolves this issue) is there another route I can take?
My guess is it's only a single registry key or DLL that says 'I'm not HTML5 compatible' but I don't have any idea how to find it.
If you have Adobe Flash installed but you do not have Windows Media Player installed, then it makes sense that HTML5 video won't play but Flash video will.
Windows 7 N exists solely for antitrust compliance purposes in certain European countries. Unless there is a specific prohibition against doing so in your environment, it would make the most sense to deploy Windows Media Player to all of these machines. Without the Media Feature Pack, you are running a non-standard installation of Windows.
It is entirely possible that installation of an alternate media player such as QuickTime or VLC may also enable playback of these videos in a browser, but this is not something that I have tested.
