Ok guys heres my dilema, tomorrow I have to put on a 20 min demonstration about 1920's film, I better pull something out of my ass quick because I know 20 mins is hard to cover on something you know so little about.

The task at hand seems simple enough, find a clip from a 1920's movie.. can anyone help me do this? I must be able to save it to my hdd and it has to be in a format recognizable by school computers mpeg etc. Can anyone help me whatsoever?
