all cd/dvd drivers are updated

[billyo]

just got done updating all of my 4 drivers, in mstudio it shows read/write , ( yes/yes) on all 4's,but when i imported a song using my int. drive, ( used to work )and played just a blink ( didnt play ) the rest worked fine, but in hoster, my int drive. and the pioneer drive shows read ( yes) write ( hide ) then i clicked on " detect again..it shows yes/yes..but when i click on pioneer drive to use as my default drive,,it wont even show up on the default drive slot..keeps going back to my plextor..kinda weird ( all 4 used to be able too )
