I got my new HR54 today. Upgraded from an HR21. I noticed that this has very little connectivity and far as component cables, phone jack, etc. First question, what function does the A/V out serve and what type of cable/connector do I need if I were to use it? Not much out there for manuals other than a generic Genie manual. Anyone know a link/website where I can get a manual for the HR54? I'm sure I'll have more questions, so stay tuned!
