For listening to pre-recorded CDs or DVDs, I know of no reason to use analog connections from the CD - DVD to the 950, as the CD - DVD should have an optical connection. Alternately, you could use the digital coax--I think some debate over which has superior quality, coax or optical.

The 950 will be set to look for the single optical (or coax) connection for both CD and DVD.

The only complication may be the DVD recorder. If you are recording from an analog TV source off cable or dish, you may need to have an analog / RCA connection / composite connection from the recorder to the 950 to listen to the recordings. Gonk has a similar set up, and I'm sure he'll be along directly to tell you if this is necessary.
