When I finish watching a recorded show and delete it, it goes back to the Recordings section, but puts the cursor at the current day! I am catching up on shows recorded over a week ago, and having to scroll back 12 days to get back where I was is a PITA! Why can't it return to the date I was at before watching the show??

It does that to me too.  But only sometimes.  Usually it stays on the same day.

Sometimes when I delete a show recently recorded, it dumps me back to a show recorded in April. (It does not depend on the deleted show having been the first in the list. The deleted show could have been sandwiched between other recordings.)
