I also have a 880 I use for my main setup but I would like to use the 745 for my Master Bedroom setup - I've got an Olevia LCD 232V which as one "Source" button to change inputs in sequence - I used to know how to program in hex codes (which I have for this TV's inputs) into an activity that would act as certain buttons that were not on the original remote - can anybody refresh my memory on how to do this? - I'm using the older software that goes with the 745 which Logitech still has on their website - any help would be appreciated - Thanks...

The Harmony dataset for the Syntax-Brillian Model Olevia 232V has many input discrete commands. You need to re-configure the device (not the activity) input settings (Device > More Options > Adjust inputs) to use the discrete method (Method 2). Don't forget to test the discrete commands in device mode first. To find out which LCD label names correspond to which discrete commands, check the device button mapping (Device > More Options > Customize the Device, Sound, and Picture commands for this TV). The custom LCD keys are now called "Additional Buttons".
