Thanks so much for your help. I think I’m gonna hold off on the .flac thing for now. I think I will set up a separate iTunes library for my lossless collection and translate the .flac files to Apple Lossless.
With that goal in mind, per your instructions I changed the SSC Codec Type to “alac” and I’m still getting the “unable to play…” error on the SB when trying to play the apple lossless files. This is very frustrating since it was working before I started changing stuff in the three fields.
If you can help me get the Apple Lossless back and help me with pointing FF to the right place on my external hard drive…I would be most appreciative.
