Hi, thank you for your replies. In the Tools --> Options --> Transfer --> Atrac Media Device --> Transfer settings, I chose the "Standard Transfer Mode". In the Advanced menu , for the "Standard Transfer Mode Settings", I selected : "do not transfer if format not supported". However, I find the transfer rate is really slow on SS 4.3, compared to Connect Player. for the same album, transfer takes: -8 minutes using SS 4.3 !! -30 seconds using Connect player. I like the SS 4.3 user interface better, so I would appreciate to use it, but transfer takes really too much time... Do you have any possible explanation ? Thanks again.
