I just examined a recording made from a similar signal, and this time there were no extra markers at all. It's not easy to explain the other event; there were markers in the middle of sound, so it wasn't smply that the unit was in Synch mode. One difference this time was that I used Hi-SP rather than PCM mode; some further investigation is warranted.

Thanks for alerting me to this topic after I posted elsewhere about a similar problem - i.e. my Sony MZ-NH900 insets irregularly-spaced track markers anytime I use the optical line in, even though I have Synch mode turned off. It makes the deck useless for much of my recording, as the tracks do not seamlessly recombine. Is there any hope that Sony can *repair* this if I send it in under warranty? Are we just "screwed?"

Did this work? I had the same exact problem (MZNH900)... and I did not have Synch mode enabled - at least it's "off" now and I don't recall ever changing it. Online Sony service told me to send it in for repair, though I didn't think to mention that I was using the optical input. Also, I would get track markers in the middle of music. Worse, when I recombined the tracks, there were repeated segments. Are there any other possibilities?
