I need the picture to be >fullscreen without getting stretched. So, you want the picture cropped to the screen size? E.g.: If you have a video that is 16x9 and you have a 576x432 screen you can: (1) Scale by a factor of 36 in both dimensions, maintaining aspect ratio, to a 576x324 video and add 88 rows of black pixel padding to fill the rest of the screen. (2) Scale by a factor of 48 in both directions, maintaining aspect ratio, to a 768x432 video and delete 192 columns of data by cropping since it can't all be displayed on the screen. (3) Scale by a factor of 36 horizontally, and 48 vertically, stretching the image--changing the aspect ratio by a factor of 4/3, but giving a exactly 576x432 video. Most video players with a full-screen mode do (1). Many have an option to do (3). I've not seen a GUI option for doing (2), but I'm sure there's a command-line invocation of mplayer (and possibly others) to do it. #2 is somewhat crappy, since it loses data. It has certainly been used, as part of "pan-and-scan" conversions, but they are usually human assisted, so they can avoid cutting out important events. (I can imagine a full automated pan-and-scan but I don't know anything that does that, yet.) -- Boyd Stephen Smith Jr. ,= ,-_-. =. firstname.lastname@example.org ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/
