I've stumbled upon a number of YouTube videos that don't give me an option to choose the video quality (the only option being 360p). I'm sure they exist in higher quality, because I've successfully tested them in a Win browser (namely: the newest Chrome). What seems to be the problem and how to avoid it?

Here's a list of things that I've tried so far:
- spoofing as different browser
- enabling OWB to use all kind of video codecs (in OWB Prefs/Media)
- logging in and out of YouTube
- deleting cookies
- spoofing using the alternate method (setting the newest possible Chrome/Win user-agent as env variable when starting OWB)

And here's an example video I've been talking about.

There are more people in Poland with the same OWB problem (zukow somehow doesn't but we don't yet know why he's the only exception).
