I have an interesting problem. A show that my wife records daily via OTA has not been recording properly for past 4 days. The channel signal is good, I watched it just prior to the recording today. When you attempt to play the recorded show back, the screen goes black with just the progress bar at the bottom and does not do anything. I scheduled and successfully recorded a hockey game on the same channel yesterday. Is this possibly some type of corruption in the series recording list?
