Play All function in Vista

[eratik]

I have Winamp set as my default player.

When i'm viewing a list of mp3's with windows explorer and click 'Play all' displayed on the top title bar it opens Winamp fine. But when I'm viewing at a list of mp3's and theres a .m3u playlist file contained in the folder the 'Play all' function opens up Windows Media Player.

My question: is there a way to enable Winamp instead of WMP to open when I select the Play All button of my windows explorer when there's mp3's and m3u's file on the same folder?

Hope you understand what I'm talking about.
Thanks for the help.

Maybe the m3u extension is not associated with Winamp?
You can run Winamp, hit CTRL+P to bring up preferences, go to General Preferences > Files Types
Just hit the All button and it will associate most of the audio, video and playlist file types to Winamp.
