Everybody may know this, but I didn't. Last night on my HR21 I was watching American Idol. Once I caught up to live time I went into my List and started watching The Biggest Loser. At the first commercial break, I hit the previous button to go back to Idol. I finished Idol and because I had it set up to record an extra 15 minutes I wasn't at the end of the recording. I pressed info/more info and deleted from there. Oops. It didn't delete Idol which I was watching, it deleted Biggest Loser.
