If you are looking for software or instructions on converting audio file formats you should take a look at the forums on the website for the Squeezebox (slimdevices.com). It's the only other forum I read on a regular basis. I'm using a script called flac2mp3 and the programmer posts to those forums. This script will take a folder of flac files and create a copy including all folders underneath with a folder of mp3's in the same structure.

I currently have a Squeezebox in my living room, bedroom and car. These will be my favorite gadgets for a long time I think.
