Something is going wrong with those Dailymotion links. Some don’t seem to be dead.
Example:
If I go click on the link in the comments, the clip works fine for me. If I click on the link in your list of broken links, I get a page that says I need to log in.
I’m not logged in, btw.
I’m not going on with those now. Can you fix it and post a new list?
Damn, my bad. I didn’t expect them to treat their links so confusingly. Some videos can be accessed both by id and by a full link (with a redirect to an id-only url), whereas others must be accessed through [a full url] (http://www.dailymotion.com/video/xm8je0_penitentiary_shortfilms) (which redirects to a longer id), links only with id fail. It’s probably related to video privacy settings. And to make it all worse, dailymotion is blocked where I live, so I need to fiddle with unreliable proxies.
