they are formated different. i found that out when i was trying to copy a news story from tv for gaykir. i tried both the audio and the data cd's ( both were new) and had to finally get a dvd-r.

then i tried to use the dvd-r's ( new, i bought a whole stack ) to record lil'monkey's audition music and that wouldn't work.

i'm sure someone...moi? while chime in.
