standard size would be...? 720*280 worked fine for me IIRC. It was an MPEG-4 file, not H.264. I must say, though, that I usually make 'em 4:3 for the iPod using iSquint. (So I keep a "good" copy at original aspect ratio for the beamer and future keeping and an "okay" one at 4:3, 320*240 for the iPod, which I often delete after seeing it. I do them before I go on short trips, for example.)
