Some Videos aren't downloading

[Dbone29]

Some times gotube only creates a null byte file.
For example when I try to download this video: https://www.youtube.com/watch?v=W0v9n5RQRto
I came from germany. Maybe this information could help...
I can watch this video without a problem in the browser.

Hi Daniel,

Thank you for reporting this issue. I have looked into it but couldn't find anything that can lead to this problem.

If you check the source file of the YouTube page, you can see a bunch of stream media urls in the json structure "ytplayer.config = {xxx}". The urls for this given video is as structured as the others which don't have this problem.

This mechanism of YouTube is a black box for us. We wouldn't know how YouTube deals with these urls and why some of them work but some don't. I'll keep looking into it, but I cannot guarantee that this problem can be solved in a short time, or ever.
