OT (sort of): Violent Wildlife DVD

[nobody]

A long time ago, late night on TV, I saw a commercial for a compilation DVD of "the most violent animal attacks." This was aggressive wildlife footage of animals attacking other animals. I'd like to see this DVD, or another like it, but I haven't seen the commercial since, and I can't seem to find anything similar on Amazon.com. Does anyone have any ideas on where I should look, or any recommendations on DVD's I should buy?
