i know sometimes when they arent getting a signal or its too low to detect, it will start a new track when they signal is picked up again. i'm not sure if this can be disabled or not,i have to hi-md units and its never happened to me, but then again, i usually do loud shows and once i hit record initially, its not quiet enough to make this happen. i'd call the sony tech support hotline,the number is in your manual.
