Blankhi folks trying to help a friend with an amateur do project.he wants to record a bluegrass cd with a voice commentary be fore each track. he has lets say all 10 music tracks in his music folder. he wants to record 10 commentary tracks. we had some success recording the commentary tracks. to do this what we did in a test run was to use sound recorder in programs/entertainment. no problem so far we recorded a snippet commentary and saved it in his music folder. the problem seems to be that the commentary file is a .wav file.when we took commentary 1 and track 1 and tried to burn onto a blank cd, windows says there is a problem with the .wav file. tried to burn an audio cd after changing the commentary file from .wav to .mp3 but got the same error. tried making a data cd recording again with the commentary file changed from .wav to mp3 but although the burn was successful the cd will not play the commentary file . any ideas? regards Paul H
