Just setting up a second AV system around my computers - XP PC, iMac, Denon 3802 with 4.1 +2 speakers, PS3 and Samsung T220HD TV/monitor. This TV/monitor is proving to be a real pain. Harmony database shows what appears to be discrete codes for all the inputs, except "DTV" (on-board Freeview). The original remote has 2 input buttons - one to toggle between analogue and digital TV, and one to cycle through the AV and PC inputs. The Harmony "discrete" codes mostly don't work. The "DVI PC" code actually selects the "VGA PC" input - I'm using DVI. Any unused/powered off source inputs are skipped, so method 1 can't be used. The best solution I can find is to use method 2 (device has discrete codes), and select HDMI 1 as the input for every activity that uses the Samsung TV. For activities that use the PS3 (DVD, games and CD), this is the correct input. For the PC activity, I added a "source" command to the start of the activity. This takes the TV to the next AV input, which is the last-used PC input (DVI in my case). For the TV and Radio activities (both using the Freeview tuner), I added a "TV" command to the start of each activity. This takes the TV to the last-used TV input (DTV in my case). Using the HDMI 1 input as a "placeholder" seems to work as a known starting point for all the activities with this TV. If I get a chance, I'll download all the Samsung codes to my Pronto and see if I can find some better discrete codes that actually work, then pass the info to Logitech so that they can update the database. In the meantime, anyone struggling with a Samsung T-series, give the above method a try.
