I used Xine-0.9.8 and Mplayer-0.9pre1 and never avifile.They are excellent players and I could play all of my videos with them. But when I tried to playback a quite huge divx 768x576 with 1392.71 kb/s, xine and MPlayer sucks in my Duron 800. I tried with WMP7.1 in Windows and of course the result was worst. So I tried avifile 0.7 and now I work only with it. It played my video very easy in fullscreen. Now I installed 0.7.3 . Even better.
