I do not know if these are issues dealing with the latest CE release, (Ox197) for the HR20-700, but they are things I would like to see improved.
1) when I pause programming, the directv screen saver turns on after a few minuets like normal. However, as the Directv logo is moving around every 30 seconds or so, it flashed back to the paused programming for just a fraction of a second.
2) For the programs that do not start on the half hours (at 2:15 instead of 2:00 or 2:30 for example), there is an issue in the guide. (I will try to explain this the best I can).
Take for example there is a program that starts at 2:15, and the time is now 2:20, in my R-15, it will not allow you to select the program that finished at 2:15 but still showing up in the guide because it is still in the half hour of 2:00-2:30. In my HR20-700 you can still inadvertently select the program that is no longer on and it takes you to a screen that says "This program is no longer available". In the R-15, as you scroll to highlight that program that is done, it actually highlights the one that is actually currently broadcasting on the channel.
3) (This one really bugs me). Ever since I have had my HR20, for a week now, it has a hard time getting a good signal on my OTA antennae. My H20 picked them all up with adequate signal. This HR20 picks up only half of them. I have an amplifier on the antennae, so it is not an issue of not having good enough signal. My H20 was pulling in all the channels at at least 75% strength on the weakest one, and the HR20 is getting under 20% on the channels it is not able to pull in.
4) I know this has been mentioned before, but I will make my name on the record as well. I would like to see the external hard drives that we plug in become additional space on the HR20. I do not like that it is seen as the only space for storage.
I am guessing your H20 is a -600 model. It has a much better ota tuner compared to the HR20's.
