I know you can put them in your favorites in your YouTube account, but I don’t think there’s anyway to download them…which would enable you to burn them to disc.
I don’t know if there’s a way to capture Flash video’s online or not, and if it would just capture the Flash. It looks like that’s what YouTube uses, which is why I’m mentioning that. I think if you can do that, you can probably get it.
They probably do it to keep the MPAA and other groups happy (relatively).
Alternatively, using a P2P app might net you some results, but that would depend on the video’s popularity.
Oh, and I did move the thread to General Software since it fit better. I left a redirect that expires in a week, though.
When an admin or a mod moves a thread, they have an option of if and how long to leave a redirect in place. I typically use a 1 week expiring redirect because either the thread’s finished itself off or the person should know where it is after a week. You don’t have to do anything.
