evanh: Well, the display resolution is not even slightly relevant to this conversationWell yeah it is, though not necessarily related to your specific issue with the EPG.
The EPG is slow at changing through items when they are not on the page. What I'm saying is, the EPG appears to have been developed to be very clear to read, especially on a smaller TV. I think they could now release a newer version with more content on the screen. The HD resolution gives more screen real estate and this could be populated with more info which should make it faster to navigate.
Or, they could release the EIT data a bit more and we could use the native EPG of the magic box itself which would be super fast, but that's another story.
