71.0 gigs, but almost all of my movies are a mere 700 megs, and I haven't watched half of them yet.
I have:
26 DVD rips
97 episodes of Family Guy (well, except for the most recent ones, but w/e)
171 episodes of Good Eats (don't even say Alton Brown isn't a hunk)
52 episodes of Magic School Bus (Thelis has it as well...)
44 random New Yankee Workshop videos.
