Ayu videos on YouTube... not working?!

[Chibi_Venus]

Alright. Everytime I add an Ayu video to my favorites list, it suddenly becomes unplayable. It always says in bold, red letters next to the title "video unavailable."

Click if you'd like to see. I'm like, what the heck? All of my favorite ones are unavailable!

So why does this happen? Is it because of copyright reasons? Am I the only one or has this happened to someone else? Is there any way to see these videos again (besides downloading)? Why am I asking YOU all of these questions?

PS: Just one more question. Is this in the right section? ^^;;
