I have a pretty new Hopper, replaced my 622. Mostly a good system, but when playing back from the DVR - even if it's just like having skipped back a minute in a live show - the audio sometimes drops out for a few seconds every few minutes. This isn't in the recorded program. I can skip back and the dropout won't be there at the same spot. So what I know is: It only happens when the Dish Hopper is the HDMI source; not when my Oppo or other sources are. (I'm not using optical or analog.) It only happens when playing back from the hard drive. Direct-from-Satellite doesn't do this. It isn't a recording problem, because it's in different places when playing back the same programs. Therefore, it's not the HDMI cable, the audio receiver, the TV or even the Dish tuner or recording codec. It doesn't seem to always happen on playback. I'm not sure what the secret sauce is - everything should typically be turned on in the same order, for example, because they happen by macro. But when the problem is there, it survives changing audio sources back-and-forth. Any ideas? This is annoying. Thanks.
