I just cloned to download my watch later list.

I added a print statement which says the url it's trying to download is:
http://www.youtube.com/feed_ajax?action_load_personal_feed=1&feed_name=watch_later&paging=0

I use 2-Step Verification, might be the problem?

Thanks for reporting, The 2-Step Verification's probably the problem, I have just tried (I don't use 2-step auth) and it works without problems. Moving to #1336.
