has anyone else had issues with the 2900 digital output? When I play back burned dvd-audio and output the digital signal, I only get sound out of one channel. I honestly didn't put much effort into fixing the proble b/c the output was to a Denon receiver and I can't imagine that it does a better job with the d>a conversion than the 2900, but since we're spending escott's money, I want to be sure that the music fidelity dac is going to used to its full potential when we are listening to live 24/96 dvd-a's.
