I am going to ask like Pooh does with the honey- is there anymore ? -Rabbit says no, but you guys always say :yes! Thanks again Jerry and Allen, I just said thanks again to Lee. What would we do without you? Maybe I shall end up a diskjockey , even randomly playing songs. Before I leave tomorrow for OLD EUROPE, I shall have all this neatly sorted out in my brain,and when I come back, I'm sure, it will have vaporized in my head -- but--- I will still have your e-mails. - Question again: my computer says I can import in Audio CD mode or in this MP3 format. On the burn side it says: MP3 or AIFF or WAV. It doesn't say audioCD. So I guess I can only burn in the MP3, not knowing what the others signify or whether I even have them in my computer's insides. And to tell the truth, I am not all that much into playing CDs. My curse is that I always want to know more about things than I need.
