Being a late-adopter generally means things work, or that someone has figured it out already. I picked the right week to try getting my Sony Net MD running with a Win 7 64-bit box. Sony discontinued their software for this 2 years ago, and the latest version will not work. Until last week, nobody has gotten it working, and I suppose lack of demand for this 10 yr old technology didn't help.
