Don't want to derail the thread, but has anyone found out just what any DirecTV HDDVR is actually doing when it is not changing a channel quickly ?
Reporting to NSA? Spamming the neighbors with Viagra ads? Morris dancing?
(I'm expecting an HR44 any day now, and will likely send back at least one HR21, and that one has had weirdly variable channel changing times. Sometimes quick, sometimes slow, and sometimes dead slow, and then most annoying of all, dead slow followed by machine gun rapid channel changes past the one I wanted to stop at)
It's a very old problem with the DVRs. If the demands on the processor and/or memory exceed their capabilities, they become sluggish, if not unresponsive. Pre-HR24 series are particularly vulnerable. Bad coding can cause any DVR to get sluggish periodically. Since getting the HR44 and HR24 (2 of them) about a month ago, I've only seen a brief (and I mean very brief) period of sluggish or non-responsive behavior. Other than that, both the 24 and especially the 44 just fly.
Since the software seems to show ever increasing demands on both processor and memory, we may face the same thing in a future software cycle. In the mean time....enjoy!
