I've recently gone thru the experience of converting my cd collection to both FLAC and variable bit rate mp3's. One of the things I learned about (sadly half way thru the process) was Vortex Box (http://vortexbox.org/content/134-About-VortexBox). Basically it's a headless OS you put discs into(cd,dvd, or blue ray) and it automatically rips and tags them. Music goes to FLAC movies to MKVs. You can also mirror those formats to others. It's pretty slick, it would have saved me a lot of time.
