I'm trying to program my 6100 to work with a LG VCR/DVD player. I understand that LG has the same codes as Zenith. I have programmed the remote with code 747 to operate the VCR, but when run through the setup to program the VCR to turn on automatically from the Program Guide, I receive the message that Code 747 is not in the database. Well, the User manual states, in fact, that 747 is a valid code for Zenith VCR's. Any help would be great.
