Complicated HDMI connection question??

I have the LHT9654S HTS connected to a plasma via an HDMI connection. I have to leave the TV turned on to listen to a CD. LG support indicated that I don't need to have the TV turned on, but if I turn the TV off the song stops. They also indicated that an Ipod will not work with the unit because an Ipod requires software to run. Does anyone know why I have to keep my TV on and is it accurate that an Ipod will not operate on this system?

HDMI has an additional feature built into it that allows for control, but most people are not familiar with it. HDMI transmits Digital Video, Digital Audio, Control, and Auto Formatting when compliant products are connected. Here's basically what it means. LG, Panasonic, Pioneer, and Samsung at this point are the main brands that support this. If you put a DVD/CD into a compliant player and have the HDMI connected to the TV then the control feature takes over - Meaning when you hit play on the DVD the TV is activated as well. There may be a menu option in your DVD player to Deactivate this, but I'm not 100% sure on being able to deactivate it.The HDMI cable is currently ahead of its time, but manufacturers haven't come up with a standard yet that all follow. I do training Nationally for Monster Cable and this has been a concern with some people. Some brands are doing one thing, and others do something else. With HDMI connected between your devices, you will more than likely have to have the TV on at all times when using a DVD or CD.Hope this helped.
