The software doesn't allow input setup for DVD devices (and I'm not sure the method Oppo uses for quasi-discreet input selection could be accommodated anyway because of the 2-second delay required), BUT...
You can add the necessary input commands (with the required delay) to to your activity startup command strings on the Custom Actions screen.
From the Oppo 103/105 IR code spreadsheet:
So... in the Custom Actions setup screen for a particular activity, you would add an "INPUT" command, then a 2-second delay, then the number required for the desired input.
If you wanted to normalize the unit back to standard Blu-ray at the end of the activity, you can similarly add add an "INPUT" command, then a 2-second delay, then the number "1" to the Activity "stop list".
BTW, if you haven't already discovered the Custom Action screen, it can be found at Activities>Settings>Review Settings>Yes, but add more control... after a few Save/Next clicks you end up at Custom Actions.
