Is this really supposed to be a video?

The music plays along with a static photo on all platforms I tried.
The thing is: it only plays when the two config options mentioned before are set to "false". But then, not a single video on Youtube can be played with a 720p / 1080p resolution. And there are a lot of other videos (real videos, not music playing alongside a static picture) which won't play when highres HTML5 is enabled in Firefox.
Using Flash rather than HTML5, both cases just work.
