Thanks for all the answers.
2 folow-up questions:
1. so using -monitoraspect 332:209 basically delegates the choice of
aspect ratio to mplayer, correct? I just tried both that and 1.78, and
both of them result in 1.33:1 aspect being used. The bad thing for the
DVD i just tried is that there is a lot of unused space in 4:3 aspect
ratio on both left-right and top-bottom (almost half the screen is
black). And while indeed 4:3 aspect ratio looks better for it than 16:9
which i tried manually thru gmplayer menu item, it is only nicely
viewable in xine where i can utilize most/all of the black space using
Alt+z and Ctrl+z. I'm not aware of similar shortcuts in mplayer.
2. which monitor would you guys prefer: the one with max resolution of
1280x800 (but it doesn't support 1280x720 or any other 16:9 pixel
ratio), or the one with max resolution of 1280x720?
