I think the PVR device characterization needs some additional options to allow for devices like Replay that integrate all of their inputs into one guide. For example, I need to be able to choose from multiple service providers, ie DishNetwork AND my local cable. Currently I can only pick one or the other. I also need to be able to tell it that this device has no need to select different inputs, since Replay will make that selection based on the channel I pick. Finally, I would like to be able to change the icon for the activity associated with Replay to something other than the Tivo icon.
