Advertisements Hello - in the past few days, I've noticed some strange behavior on Dolby Digital audio output on my HR10-250. I've always had it set to record and output on Dolby Digital without problem. I'm also running 6.3c. Here's the situation: On some recorded programs, I get no audio output but if I switch to Dolby Digital on PCM, I can get audio out. On other programs, I get normal audio out on Dolby Digital, but no audio on commercials! On commercials (or on the whole program if I'm getting no DD audio), I hear a low, muffled rumble-type sound, but nothing else. This only seems to happen (from my recent experience) on NBCW HD (83) or the local NBC OTA HD (SF 11.1). So, it happens on both OTA and satellite, but only on NBC and, I think, only on network programming (that's all I'm recording). Has anyone else experience this? Any suggestions or thought? Thanks!
