In the OS X 10.1 version, I need to trash the user prefs in the /lib/prefs directory, or the program crashes on my Dual-USB iBook with Griffin iMic. Also, comment on the DSB-R100 Hardware: it needed a ferrite toroid to keep the USB conducted emissions out of the tuner, and it has distorted audio on stations with higher FM deviation. D-Link could have done better for 50 cents extra components. NICE SOFTWARE by PTH though. Just need to resolve the prefs problem.
