Playlist extensions

I have Roxio Record Now 9.  In the window MP3/WMA Disk Project Settings, Presentation Formats, (control of playback settings), there are boxes to check; M3U, pls, wpl, High MAT, MPV, and XPSF.  I understand that these are playlist extensions. and that different players use different playlist formats.  Which is the best extension to use for the SanDisk Fuze?
