Howdy, I'm currently using a Yamaha DSP-A3090 (predecessor to the A-1) fo my main setup, and am now finding it (seemingly) to be obsolete in terms of passing a Dolby Digital signal. It has one AC-3 RF input, which in turn requires a coax RF output from the source (LD, DVD etc.). This configuration also requires an audio (analog or optical) connection, which worked fine with my trusty Pioneer LD player. For years, I've been able to work around the issue, by having the Denon DVD-2000, which had an on-board DD decoder. In changing to a Pioneer Elite DV-37 recently, a player that has no built-in decoder (but passes both DD and DTS via digital outputs), I see no way to get the DD signal given the Yamaha's connection options. Does anyone see a remedy that I may be missing? Has the "RF" input gone the way of the dinosaur? Given my current dilemma, I'm thinking about purchasing a Denon AVR-3802. Do the current crop of A/V receivers with built-in decoders merely require connection to their digital audio inputs to get DD and/or DTS, or do they also require an additional step? Thanks for any assistance in advance.
