I got annoyed that my avi's were skipping the other day, and thought they looked like crap without post-processing, so I wrote a little patch to dynamically select the output quality based on current CPU usage (at least for DivX, OpenDivX, and MPEG). Skipping goes away, and most of the time stuff looks good. The patch is to mplayer.c from the 0.17a Ideg Counter version, so you'll probably have to do a little work to apply it to the current version of that file. 363a364
