I'm setting up a 670 with an old Panasonic TV that only has 2 source modes, tuner & video1. It has a toggle command to select between the two (none of the discretes in the DB appeared to work). Everything works except for one bit of weirdness ... when switching between activities it always toggles the TV input even when it doesn't have to. E.g. switching from Tivo to DVD, it will send a TV/Video signal twice rapidly, cycling to tuner & back to video1, even though in theory it doesn't have to send anything. I thought Smartstate was supposed to handle this? It's not a huge deal but can I get rid of the unnecessary double toggle?
