How do I use the commentary track from the deluxe edition?

[Stalkers]

It's just an MP3 file, so I guess it's not a "director's cut" thing I can use with the game, or can I do that any way? As far as I can tell, it's the designers talking about the game for four hours, right?

They're MP4 files and should be viewable in whatever your default media player is. They're videos of the game being played, with the developers commenting on the action.

Aaaah, I see. I started them with Winamp, which doesn't display MP4 video. Now it makes sense.
