Will gladly include any additional required info. Appreciate your attention.

This problem should be fixed in the current version (2013.09.16) of youtube-dl. You should be able to update using sudo youtube-dl -U. If that throws an error message, can you tell us how you installed youtube-dl?

By the way, thank you very much for the great error report. You can save a lot of work by just including -v or --verbose in the command line - that will print everything (and even more hints to what went wrong) all at once.

I'm closing this issue now since I'm fairly certain that 2013.09.16. If the problem persists, please comment and we'll reopen this. Again, thanks for the great report! We're thinking of an automatic update mechanism.

Issue is resolved. I must say I am amazed by your quick and to-the-point reply. Keep up the good work and many thanks! Cheers.

Sorry, I saw the stackoverflow question just now. This issue tracker is indeed the better place to report problems with youtube-dl. Researching video patterns sounds like a really cool application. Would you mind dropping me an email when you publish your paper?

Hmm.. sometimes this runs smoothly and sometimes this happens:

Run sudo youtube-dl -U, until we automate the process, we'll need to make new releases each time Youtube changes the algo.
