All the learned codes you need from the factory remote. The DTV1080 is tricky to learn on the Neo, so this should save you some time. Note: it does not support discrete on/off codes. Per an email I received from a Sr. Product Manager at Zenith they are looking at providing discrete capability as an upgrade.
Modified version of John Joseph's CCF with discrete power and HD/low-def macros. Note: HD-out macro returns the unit to the previously set (1 of 6) available HD output types.
