I think this is what is happening, so I could be wrong!
You are trying to make an
AUDIO CD so ezcd is automatically converting the
mp3's into
.wav files and therefore restricting the amount you can record to the capacity of the cdr i.e 74 mins. I think you need to just make it as a
data cd therefore the amount you can put on will be restricted by the cdr capacity i.e
650mbs and not time. Try it and see. Hope that helps.
