I must admit to have not played under the hood of mine.
I just went out and shot!
I don't even know how to do video yet! to be fair not had a lot of time, if it's in my hand I want to use it, not read up!
That's cause you're confident! 
I had to get the focus button switched, was doing my head in
It's dreary and I'm working from home at the mo' so have to do something
Have you got yours gripped? How many shots do you reckon on a single battery charge? I'm thinking if I need 2 more.
I read a thread here and some say 600-800 some say 2000! I bought the cam for wedding in a couple of months and will have it gripped by then. I might keep it a bit longer though
Enough for a full days shoot? I should get 2 more batts just in case?
Frickin' expensive though. Digital Rev have a 3rd party batt for the 5D MkII, apprently fully compatibile.
