The manual has no predetermined codes for either digifusion or Oppo and I am uncertain if you put in the code for a source (1000 for a tv for example) and then try all the Panasonic TV codes, or just try each code on it's own. It is also unclear to me at least which buttons would control which function on either the Oppo or the PVR.
The teaching process appears to require a remote which hasn't been eaten by a Newfoundland!
