One of the great things for Auto Tune for me is to use it as a reminder. With my HD receivers I do it all the time. I will start flipping through the guide and see a movie or something coming on that I want to watch that is starting in 20 or 30 minutes so I set an Auto Tune to remind me so I don’t forget about it which I do all the time on my HR20’s because they don’t have Auto Tune. Now if I set them to record I may not see the record light come on which happens all the time because where I have my equipment sitting. So at this point I have forgot that it was on and I am not watching it. I do have it recorded now so I can watch it later when I get a chance but don’t know when that will be so that kind of sucks. Plus I am sitting there watching something I don’t really want to watch just to pass time until the movie or whatever I set the Auto Tune to come on. If Auto Tune was added to the HR20/HR21 I would use it almost daily for this.
