Hi, I'm new to the forums...and as well as being new to the NetMDs. But I am familiar with the old school MD players without the net function. I've had a mz-r37 a few years ago and I was satisfied with it throughout the time. But I decided to upgrade to a mz-nf520d. My first impression of this new unit is...UNRELIABLE. It might be just me but for some reason the software that came with it seems to be very groggy and doesn't respond to when I connect the player to the usb jack. I see a little usb connection icon on the right side of my start bar like any other time that I plug up my sony digicam, but the sonic stage doesnt seem to read that anything is being connected. I'm wondering what I did wrong...since I did install everything on the CD and upgraded it to 2.1. It also says "Please insert a recordable disc" when I go to the transfer section...even when I have a disc in the player. If anyone can help I'll greatly appreciate it.
