Problems is all I've had with my HR20-100 since I got it a month ago. I often get the Delete Now message when I first try playing a recording. Fortunately restarting the receiver and waiting forever usually solves that problem.
Yesterday I came across another problem. I was watching a football game and suddenly the skip back, REW, FF, and some other keys didn't work. I thought at first my batteries were weak in the remote so I replaced them but that didn't solve it. Fortunately I have an HR20-700 and started watching the game on that while I once again restarted the 100. After the 100 came back, the keys worked again.
Now I think it's time to call in and get a replacement.
