This happens to me when a CDN network substitution is either placed or pulled from the American channel. The only way around it is to FF one minute past the sub point. But PBS? They rarely have subs placed on the, so this is odd.While watching a recording of "Vera" from PBS Seattle, ~25 minutes in, the recording stopped and the screen went to PVR List. Numerous tries could not get the show going more than a few minutes in. Same result after doing a panel reset. I hope it was one-off recording problem. I really would hate to ask for a refurb.
