I didn't quite understand the question, but I assume by "CD or MP3" you are referring to quality. MP3 can be encoded at different rates, equal to a CD or far lower for limited bandwidth transmission. The file itself would of course give a clue in the extension - .wav or .mp3 right click and choose properties, does that tell you anything? js ----- Original Message ----- From: "Steven Smolian" <[log in to unmask]> To: <[log in to unmask]> Sent: Saturday, April 01, 2006 5:12 PM Subject: [ARSCLIST] Windows media player 9 I've just started using Windows Media Player 9 to be sure the MP3s I make for web distribution actually play back. Does anyone know how I can tell if what is being played back is CD or MP3? I can't seem to find a screen clue. An email of this question to Microsoft costs $ 99.00!!! Phone suport is $ 250 per question.!#?/ plus all the rest of the comic book explitives.
