I have WMP 11 on Vista Home Premium..

I select Audio CD under the Burn menu, drag some files, and it converts them to .wav files on the CD, which are the regular Audio CD format.

I know my car stereo is a little fussy with CD-R's (had 1 or two brands that often didn't work), and my old DVD player wouldn't read any CD-R's or CD-RW's.. but your PC should still be able to read them for sure after you burn it.
