Original Poster here with an update -
Now I am really confused, this morning I turned it on and ta-da, it worked. No attempt to download software, it just came on just the way it is supposed to do.
Funny thing is the last software downloaded version and date/time still has not changed from what it showed on the 20th.
It unsuccessfully attempted to download new software on Sunday, Monday, Tuesday, Wednesday, Thursday, Friday and then suddenly on Saturday it didn't. We didn't move, we didn't change the dish, or the cables, or have a tech come out. Signal strength was always in the 90's everytime I checked, and I checked frequently over the past week.
We'll see what happens tomorrow.
UPDATED AGAIN:
The DVR worked fine for another day on the same set up without trying to download software so that's two days total.
Then we moved locations and changed to our traveling 18 inch round dish (same type as the other one we have permanently mounted at my Mom's house). This also meant we used a different set of cables. The next day, the DVR again did NOT try to update software. On the second morning, in another location, the DVR did download new software so now it is reading the 0x994 version.
No question at this time, just posting what happened for anyone who might be searching posts later.
