Something else they could work on is the Local Conditions screen on Instant Weather. The text is almost the same color as the background, so it is very hard to read.
Also, I agree with everyone else about the 29 minute pad on the PVR timers. I used that feature a lot to extend sporting events by more than an hour. That is going to be a real hassle now!
And when are they going to put the screen saver back, and why did they take it away in the first place?
Another one that has not been mentioned much here, is the setup screen for programming favorites. Why the heck does it not show you which channels you are subscribed to and which ones you are not in red like the 501 does? The guide does it, so why can't the favorites list do that? I have to write down the channels I subscribe to as indicated by the programming guide, and then go to the setup screen to modify the list. Very strange that they don't have that.
Finally, I also would like to add my support for the sticky menus feature. When I sort PVR events by name, rather than by date, it should stay that way!
