Re: CD, SACD & DVD-A
There is a lossless Windows Media format that has tags and moderate compression. Once you digitize your audio files, Goldwave can store it in that format. If you want to store your vinyl on optical discs, there's a format called "Music DVD" that is compatible with most of the DVD players I've seen. Roxio Creator can make those DVDs, and show the tag data along with an image for each song.
I don't know of any PC drive that will read the SACD layer either, so I have digitized an analog output from my Oppo in order to store it on my PC.
