Using the "open with" trick may not produce the desired results ;-)
Try using the easily accessible front end to change these associations:
Open WMP Tools menu Options File Types tab, and uncheck the box for "Music CD
Playback", and click OK.
That by itself *should* revert the audio CD playback to whatever player you formerly
used. If it does not, open the player you want to use for audio CD playback, and
use their menus the same way, to associate the player with audio CD.

In WMP6.4 and probably also MediaPlayer Classic, the same basic menus should be
available as in WMP9....just check the box to have one of them grab that
association.

RealPlayer has a similar menu, but it's exact location depends on what version you
have...and I don't support that player so I can't give you the specific menus. All
media players will have the options somewhere in their menus.

Ever since I installed WMP9 I've only been able to play audio CD's using
WMP9. So using "open with" and then selecting realplayer, media player
classic, or even mediaplayer 6.4, produces an error message, saying
essentially that the format is not supported. I won't list all the error
messages for now, but here's the one from 6.4:

"Cannot play back this file. The format is not supported. Error = 80040265."

The format is CDA and the CD's are retail prerecorded.
