SA-CD/DVD-A question?

OK - so i finally buy a new CD player ( in this case a Pioneer DV-48AV Elite) .This is to feed my EAD -DSP Pro- music only system.Reason for this particular purchase was that it will play redbook CD's ,SA-CDs and DVD-Audio. Went to play a SA-CD dual layer - Pioneer switches to SA CD ( which of course it won't output thru the digi out jacks ). There does not apear to be a way to overide this auto selection and make it play the redbook CD layer? Is this true for all multi-format players or do some other manufactorers offer a product that allows you to tell the player which layer to play? Second question - but do most DVD-Audios come out ogf the digi jacks as redbook CD sampling/playback signals - in other words - can I get any digi signal out of this or any other player via digi jacks when playing DVD-Audios?
