Fairly typical - had this problem when hooking up a DVD recorder to a
AVR3802. Couple of things to consider / try though:
o Using a spare optical out with an external AD converter. You'd need
something to autoswitch between the amp's analogue out and the analogue out
of the AD converter, as I don't think you'll get a digital output produced
for a purely analogue source. (maybe not a problem, depending on what kit
you have)
o Making use of the Zone 2 speaker outputs. You *may* find that you get
output from these, even if the source is digital, and would hence just have
to attenuate the signal suitably for a line level input.
The best solution however generally seems to be to provide the amp with
every output format that the source provides (both for audio and video).
Generates much more cabling, but usually less hassle is the long run.
