I need the remote code for the LG LHB977 1000-Watt Blu-Ray Disc Home Theater System so that I can adjust the LG's volume on the Tivo remote control. There aren't any A/V codes for the LG in the remote code section of my Tivo. I have two Tivo remote controls and I'm unable to get either to work in the Learning Mode. Both remotes work perfectly, otherwise. I've tried LG TV codes but none work for the LG LHB977. I've been told that Goldstar remote codes might work but none that I've tried worked for the LG. I've tried the Tive remote code search technique but that didn't a get a successful hit. I've chatted with LG and Tivo Customer support but no success with either.
