In a previous blog I discussed audio formats, and decided that I definitely prefer high-resolution audio. SACD disallows ripping, so it is not a useful format. But Blue Ray music DVDs offer a good path to hi-res audio. I bought a set of Blu Ray DVDs of Gergiev doing all of the Shostakovich symphonies and concertos, and I really wanted to stream them to my hi-hi system. So I figured out how to extract the audio in a lossless manner.
