Introduce white background for "Error loading this resource"

[MaxValue]

When using Firefox on a smartphone and watching a video on the media.ccc.de site, it can occur that a video can't be loaded. In that case an error message is displayed directly in the video player.

Problem: the background of the player is black as is the font of the error message.

Solution: set the background of the error message to white or something visibly brighter than black.

@manno I don't see how this is related to the original issue, maybe your comment is attached to the wrong issue?
