I have an old Panasonic DVD/VCR which plays DVD-Audios. It predates HDMI, so you need to use its onboard decoder. I've left it connected specifically for that purpose. The VCR section isn't even cabled!
There is a MULTI button on the remote. When you select that, it switches to whatever you have hooked into the six RCA jacks in the Multi Input section. The DSP is switched off when you select MULTI.
The tricky part was how to get the video to switch along with it so that you could simultaneously view the DVD-Audio menus, watch included videos, etc.
There is a setting in the 3900's menu system that allows you to select what the background is for that input, and I chose DVD. I have that DVD/VCR connected to the 3900 with component video.
So, it works and it's really easy.
Strangely enough, the tone control does not work when the MULTI input is selected. I have noticed, for example, that the output to the subwoofer is thin in this case. This was true on my previous receiver, so I'm not surprised.
As expected, the record out is disabled when MULTI is selected, so you can't pirate your favorite DVD-Audio disc.
