I like that the number keys can be used to input letters in the search section.
I'd like to see the addition of them also working when in "PVR" view. Rather than me hitting CH Up/Down to scroll through to find the show I want, why not allow the number keys to jump to those letters sequentially. If I want "Stargate" I hit 7, 4 times to arrive at the S section. 2 twice for B and so on.
