Buffy dailies?

[akka]

Hi, I used to post here quite a lot back in the day, just rediscovered the site.

I've noticed lately there's a lot of footage that's popped up on youtube called dailies(?) which seem to be just the actors doing different takes. The only ones I can find seem to be the ones James Marsters was in. I was wondering if anyone knew more about these, do any of Eliza exist? Does anyone know how these are getting leaked?
Thanks
