I love my HD DVR / Converter box!
I've been renting it from Cox Cable. Setting up a recording schedule is quite easy once the program that you want to record is found in the guide or the search option areas. What I would like to see (I know this is a pie in the sky idea that may not be seen any time soon) is an option that would allow someone to set the record scheduler for a program that is being promoted at the time.
Let's say your watching something that you've recorded on the Sci-Fi channel and you see a promo for a movie that you would like to set to record. While the promo is running, it would be nice to punch one of the buttons on the remote and the record scheduler would be set to record it.
OK engineers, get busy!
