I'm running a win7 pro vm in Fusion on Mac.
I've been running this setup for quite some time (since Fusion 1), first on XP, later Win7. Using the app dbPowerAmp Music Converter/CD Ripper to rip CD's to AAC, using the Nero AAC Encoder (command line program, utilized by dMC).
A year or three ago, I had trouble when writing to the Shared Filesystem, I had weird errors. Writing/ripping to a VM internal fs and the copying the files to the host works. But ripping directly to the Shared FS doesn't.
Now after upgrading to Fusion 4, this problem has resurfaced.
