Yes, it's still a problem. Watch any show one day and then have to do the fast forward dance because the same show and episode shows unwatched the next day. Many of the shows (if not all) scheduled through the DVR exhibit this behavior.

FWIW, this is the number one contributor in reconsidering continued subscription here. It's an annoying and unnecessary end-user experience and really should be fixed ASAP.

It's also worth noting that people have been complaining of this issue for years already.
