I can't believe it, but Sony got version 2.0 right! I could never stand using version 1.0/1.5 and would always resort to using SimpleBurner with my NetMD.
With SonicStage 2.0 it imported all of my 320kbps MP3s into the library and lets me transfer easily to my HiMD. The first time it transfers it will convert the file to OMG format automatically.
BTW, I'm using an NH600D I picked up at Target. I tried the remote from my R90 with this and the buttons worked but the LCD on the remote was basically blank. I'll play around with it some more.
