Hi, Bernhard and fellow sufferers:
I think Feurio isn't the greatest reader of ISRC codes. Put in a few discs (commercial discs; Pat Metheny, Backstreet Boys, etc.) and hit the "Read UPC & ISRC" command; usually the first time nothing happens. Do it one or two more times and it pulls up an ISRC for one tune only, the 10th or 13th, etc. I'm going to try to figure out another way to do it (I have Jam, might see how that reads). If you've done other testing, please post (are you sure your PC CD drive can read ISRC?)
