Yes I noticed this same issue.. very annoying.
The upgrade nuked both of my boxes. After a call to Tech Support I got one working but they told me I would have to wait for a "patch upgrade" for the other one to work.
In the end, Occassio was able to find me two newer Moto boxes (I had the old 3416s) at my local Cox office and I swapped both out.
But yes the new upgrade has some issues I don't like. The not listing all the viewings for the show you have highlighted sucks.
