I'm glad to have found this discussion. I'm having the same problems with converting mp3s to MD-playable format. I've followed all the suggestions here, but the same thing keeps happening -- no sound on some of the tracks. I know they're playing because the timer advances, but there's no sound. Then the next track plays fine. Urgh! For the record, I'm using SS4.1 on an XP SP2 machine, downloading 320 CBR mp3s to a Sony MZ-S1. The transfer mode is set to LP4. The maddening part is that the tracks that don't convert properly are from the same CD and tagged exactly the same way as the ones that do. There are no special character in the titles, nothing at all in the comment fields -- in short, nothing to differentiate the bad 'uns from the good 'uns. If anyone has come up with a solution, or even an explanation, since the last posting I'd be grateful to hear it. The only thing I can think of that I haven't tried is to use SS to re-rip the CDs direct to ATRAC and see if that works, but I hate to go all the way through that process again if there's an easier solution. Thanks for all the help so far.
