Which Blog?

I've been flitting between Blogger and another webblog site (Multiply) for the past couple of weeks. The main reason being I'm undecided which site to use. The other site enables me to post little videos of Puppy at work, which my family loves, on the other hand, I think that site isn't very secure in that anybody could easily download the videos, as I post for the public to see. DH suggested I use a site dedicated to uploading videos, which then can be played in Shockwave format. I think I shall try this out instead....nothing is foolproof to the most determined I suppose, but at least it will set my mind more at ease.
