Could anyone with this problem try to diagnose? Are timers firing? Why :29 and :59 rather than exactly at the top/bottom of the hour when the guide is shifting? Does it happen only when a lot of timers exist? Are some channels better or worse than others?
For me, it is happening right as the time switches to the start of a new program. For example, if I am watching a movie and it starts at 8:00 and ends at 10:00, the pixelation happens when the time switches from 9:59 to 10:00, but not any other time (i.e., it does
not happen at 8:29/8:30, 8:59/9:00, or 9:29/9:30).
Another example is if I am watching a movie or show that ends on a "weird" time (i.e., 7:40 or 7:01) - the pixelation will still happen when the program ends and the info switches to the next program.
It happens whether or not the DVR is recording. I have a single Hopper system (no Joeys at this time), so no Joeys are in use. I do have the Sling adapter plugged in, but it happened before I got the Sling adapter as well.
I do notice some channels are better than others - I have not noticed it on my local channels that I watch (CBS, NBC, and FOX out of Roanoke, VA), but I have noticed it on all nationally available channels that I have watched since I got Dish.
Seems like it's a software optimization issue to me - the receiver is doing something during that switchover time that takes too much resources and there isn't enough available to display the video.
That said, I've just switched to Dish from cable/IPTV and don't have much experience with satellite receivers, so it may be something on Dish's uplink end or something on my downlink end. I'm just comparing it to what happens when I try to watch a video on my computer while I am doing something else that is processor/memory intensive.
