Try enabling Model ID on the remote to slow it down. from Dtv mode enter code 963 Channel up. should get 2 blinks out of the dtv light after code and after chan up.
Model ID just adds code to the start of the remote command so it slows down response. to deactivate use the same code just channel down rather than channel up.
