Tonight for the first time in months there was an IKD (Biggest Loser). Remembering some ideas from past IKD posts, I tried a red-button reset. The Biggest Loser disappeared from the playlist. What's more, most other programs that were recorded today (1/12) or yesterday also disappeared from the playlist. They also did not appear on the history, while programs that were recorded yesterday (Big Bang Theory) and today (American Idol) and watched today and deleted showed up on the history as recorded and deleted. Only two programs (both Chef's Academy) remained on the playlist and the history. Can this be a result of a defective receiver/DVR?
