Hello all. This is my first post so I am sorry if I am in the wrong place or if I am repeating a topic from elsewhere on the forum. I am running Sonicstage 4.3 ultimate (from this site) on a pc running Windows 7 Home Premium. All seemed to be well and good, it recognised my MZ-NH1 and allowed me to initialise the discs, but when I transfer cds from my pc to the disc, it pauses for several minutes after transferring 5 or 6 tracks. I remember on my old XP pc it would take maybe an hour to transfer 20-25 cd's worth of music, where now it takes a couple of hours. I am new to all this so am I missing something obvious? Thanks very much for any comments or help
