NetMD Built in Drive

[Velo]

Hello Vaio Team

My PCV-RX413N(CE) got an optional NetMD Built in Drive.
Using Sonicstage 4.2 CP, I can´t write anymore data or music
of my legal owned recordings. Nearly all Mini Disc´s are not accepted and get out the Drive.

In rarely cases the Mini Disc is accepted, but it isnt possible to write any kind of sounddata.

thanks
