In regards to the Universal brand, can you switch "activities" without it turning things off? Presently I use a harmony 880 with the activities buttons, if I switch from say DVD to TV (cable), it will turn the DVD off, pre-pro(or reciever) off and the TV. Is it "smart" enough to realize what is turned on already? As a side note, the 880 does have some major limitations with the 970. Thanks for sharing your thoughts.
