How To Play Video_TS Folder?

[Marcos]

A friend gave me a concert data disc and I put the files on my HD. It also came with a simple media-type player program where I could go to File>Open folder on the file's folder named 'video_ts' and the movie would play. I would like to know how I can setup Winamp to do this (some setting in 'preferences'?)instead of using that little player. Thnx!
