If I enable Volume Control as well as Max Volume, I lose the ability to control volume from the buzz box using the large volume buttons on the remote. I can still control the volume from the TV to the home theater using the small volume buttons at the top of the remote which I have mapped to the TV remote. What should happen, IMO, is regardless of a channel being in PCM or DD 5.1, I should be able to raise or lower the volume coming from the buzz box from 0-25. As you’ve mentioned in another thread, I could then use the remote’s top volume buttons to set the volume top level and then the remote’s large volume buttons to “fine tune” the volume.
