When you burn a CD, it takes the MP3, then converts it to CDA then burns it to your blank CD, or you can do MP3 to MP3. Some programs like Winamp I believe will convert your CD to MP3 for saving on your HD. I'm not familiar with the "no-loss" codec but I'm sure there would be a program to take your MP3 then convert it to that format, then save it to your HD. Worse case scenario, you take your MP3's burn them to CD's then convert them to your HD in the newer format. If I knew exactly what this "no-loss" format was I could check up on it.
