Trying to debug a problem. I do not get any audio output in DVD/DIG4 mode on my Marantz SR19 unless I hit the A/D button. I see a message that states "NO data" Playing CDs in this same mode also has no audio output but it works fine when I switch over to CD mode. Previously the CDs played fine in the DVD/DIG4 mode. All other modes work great(ie. tuner, VCR).The composite video output from the TOSHIBA DVD player is directly connected to the TV and works fine. Is this a problem with my Toshiba progressive scan DVD or a problem with the Marantz.How can I find out?? I hate to have to take everything apart to bring it in to the dealer.
