No matter what other people will tell you, this player has been causing more instability to my Windows Vista than any other program I ever used under Vista. Just closing the KMPlayer window during the playback may in an instance totally freeze your computer and the only option left will be to power it off - no matter how abhor I doing that, and how dangerous it may for the corresponding file systems.

I can't believe that any seriously maintained program can behave in such a horrible manner.

In one word: plays nearly every video format and has a very good support for subtitles yet the program IS UNSTABLE.
