yep, i'm having the exact same problem. when recording analog via LineIn, it places Track Marks during "silent" parts. incredibly annoying, since i'm sure there's some added overhead with regard to file transfer via SonicStage, and that needs all the help it can get. transferring 200+ files, even if they add up to the same size as a single file, will take longer. anyway.... if anyone figured this out, or talks to Sony Tech Support, please post. thanks!!!
