Sometimes it would only lose audio for a split second, and of course the display on the Krell would change. Other times is lasted longer but often recovered. It happened on about the start of every commercial. Other stations like BBC America, HGTV, ect. are very stable and it may only happen once every week or even longer. Something about these local channels being fed via DirecTv is going on.
Just to clarify, there are 3 ways to view local channels:
1) OTA antenna feeding a TV. The S/PDIF feeds the Krell.
2) OTA antenna feeding DirecTV AM-21 (or equiv), this integrates OTA channels into the DVR guide.
3) Locals via DirecTV satellite.
When you said: >>I will also try watching the local channels with the problem via the over-the-air antenna instead of the package included DirecTv version << I was not sure if you meant 2) or 3). In my case, I have had lots of problems with our local Fox affiliate with option 2). It was like the DVR was broken. Yet options 1) and now 3) are fine. It is partially due to the OTA signals being coded with much higher bitrate MPEG2 video vs. the lower bitrates used by DirecTV (with a better codec). There may be other factors at work.
If your locals on option 3) are flaky, note that the local channels come to your dish from a spot-beam transponder, not the same as the main channels. It is possible, due to dish alignment, for differences in performance to result. But this is easily eliminated as a factor if the 3) locals work perfectly when fed directly to the TVs.
Just saying that locals add additional layers of variability into the troubleshooting equation for Krell, which might be beyond their control. If we can limit the investigation to the "main" DirecTV channels, that may make it easier to duplicate the issue for analysis.
