[linux-audio-user] SACD backup?

Greetings -- I've got two toys recently, an HP200e DVD+RW and a Sony NCD650 5 DVD/SACD/CD/VCD player. HP backs up a DVD in 5 minutes, 24 minutes reburn. Sony plays the transcoded VCDs, which are inferior and I just did it to see that fact. But with the SACD, I can't find any info on ripping it. Can I use my DVD+RW HP to read it in? And why isn't there toslink output on the Sonly for SACD -- it says it's for DVD only, and indeed nothing comes out when I use the optical, I have to connect 6 cables and switch the receiver into DVD 5.1 ch mode to hear the SACD, and then the subwoofer is surprisingly soft (even with the +10dB max increase on the Sony). Mind you, my sub is a 3 ft tall Yamaha w/Helmholtz folded tube inside, it rocks the house with DVDs... Any hints on SACD backup would be appreciated! Cheers, Alexy
