Well I have to say that I STILL see one of the issues I was seeing on the last rev. I am seeing two different things which I am certain are related, as they happen at the same time.
When I am watching TV live through the Genie Mini, occasionally I will see a glitch while I am watching in real time, the very beginning of the recording cache is viewed alternately, instead of the real-time show. This cuts in and out usually just once in the course of a single show, and is sporadic. It seems to just be the way the Genie Mini sees it - but not the main Genie HR44 unit. Viewing devices connected to the HR44 unit generally seem to be unaffected with live/real-time viewing. Or rather, I haven't noticed this happen directly on the HR44. Just on the Genie Mini.
At this time I am unsure as to whether or not it is being recorded by the HR44 that way, but I will amend this post tonight when I get the chance to check the recording.
The second issue I am seeing, which happens at the same time, is I tried changing the channel through the Genie Mini and then coming back to it. When I get back to it, the channel cache will be all the way to the left at the beginning, a couple hours behind. This shouldn't even be possible since I never use Double Play. Then I fast forward through the cache to get to the real time point in the program. There is a point along the way where it skips all the way back to the beginning of the cache. (in this case the current program segment was orange and being recorded) Using this device, there is no apparent way to get to the far-right real-time live content on affected channel. At a certain point, it consistently jumps back to a green segment, a couple hours to the beginning of the channel cache. So basically whenever this happens, I have to go to the room where the HR-44 is to finish the rest of the show.
Hope that helps someone at Directv in further diagnosing this issue. Maybe someone higher up on here can forward this to those "in the know".
