iPod batteries; Diablo II and movies

I'm just asking, how long will an iPod Touch with 32 GB last watching a movie? In battery, I mean. Because my bus ride from home to ______ lasts about an hour and a half. I was going to watch as much as I could of "the Godfather Part III," but I didn't know what to expect of the battery. Pls help.

Is the new expansion pack to Diablo II official? Because I've heard from my copy of PC Gamer that there's a new expansion pack called Diablo II: Median. Any evidence?

Are the movies "BREACH" and "SPEED" good? Why does everybody hate "The Contract?"
