ReplayTV 2020 Digital Video Recorder
It's Better than Amazon Says
I read the review that Amazon put out for this box. I have one at home (the 14 hour model) and find that I now become impatient with people whose TV's don't have these features. I must take issue, however, with the  warning that it will only back up 7 seconds when using the replay option.  What they mean to say is that it backs up 7 seconds each time you hit the  button. I've had times when I backed up over 30 minutes to catch the start  of Law and Order (though I used the rewind feature to back up that far).  This is a great product, and the price reduction is amazing (I paid around  $1000 for my 14 hour model).
