I bought the SMT-S7800 about 3 months ago to replace SkyHD. Everything is working well except for the audio replay on HD channels which have Dolby Digital sound tracks. When either replaying from a recording or playing after pausing, there is a glitch in the audio stream every 10 seconds or so. As its a digital stream, the break is very obvious and very annoying. It's such a shame as everything else is top quality. I have several other sources which play Dolby Digital at much higher bandwidths so I'm pretty sure it's not my Denon AV Amp. When watching live TV, the audio glitch is not present. Incidentally, the audio glitch is the same when playing audio through HDMI and Optical. Any ideas or does anyone else have this issue? Cheers.
