Media Player Classic an open source player, used to play any kind of videos under windows, is not running properly on wine. The application can be found at: http://www.codecguide.com/download_kl.htm I think that is a good program to test wine, since it is open source and wine developers have access to the source code for debugging. I tried it on wine-1.1.41 on Ubuntu 9.10 - 32bits and it crashed when I tried to open a video.
