This can be tricky if the manufacturer hasn't made discrete input select commands. You could try googling for the IR codes for your model of TV, if you find a list see if there is any commands for HDMI1 and HDMI2, if there is you can copy and paste them in to the driver wizard and see if the work. If you can't find the IR codes you'll have to create a macro within the driver to change inputs. When you start creating a driver, near the start of the wizard on the driver properties page it will give you an option to select "discrete input selection" tick this box if you can find the IR codes for the inputs you want, if you can't find them leave that box unchecked and you'll have to configure the macro to change inputs later on in the wizard.
