I don't quite follow what a "STP DVD" is (DVD-V?) and hence the connection with DVD-A. If you had a DVD-A, there are a variety of options for capturing both digital and analogue outputs, but you don't have the player (or is it that you don't have a stand-alone player?). Otherwise, you are limited to diving in and grabbing files - and I'm not sure of the formats that you will be able to see on a PC. Next problem: do you have a SACD authoring package that will take care of the compression and the surround-sound aspect? I personally haven't heard of SACD burners. You should however be able to play a stereo CD-R on your SACD player.
