i think winamp is the best video player as well... except for DVDs with the menus etc which it can't handle, but i tend to avoid those anyway as it's basically 10 times the file size because of the rubbish compression used for DVDs, just to keep a few menus...
although to be honest when it comes to a video player, you open the video, it starts playing, it finishes playing, you close it... it really makes little difference to me which player i use, although having a playlist is useful sometimes (like if you have a film that has been cut in half for example)
