I’m having the same problem. I’ve missed tons of recordings already. Redoing the tuner setup just fixed it for me as well. Hopefully it holds. Whatever caused it must have been the same for me. I’ve got FiOS, if that matters. And judging by the fact that you said it was a Wednesday (I unfortunately didn’t notice which day the problem started as I don’t record daily and don’t use this for watching Live TV) it could have been a good ‘ol Windows Update on a Tuesday that caused it.
