This might sound like a silly question but hey! I'm a newbie! You're supposed to expect these sorts of questions from me!

I use a Sony TV with a built in HD tuner. When using the optical out source to my 990 so I can enjoy the HD picture, I can't get anything other than 2 channel sound. Is this just a limitation of over the air HD signals? I can't readily find any info on this out there after a quick search. If there is anyone else out there that is getting HD this way have you experienced the same?

Can someone please enlighten me on this situation? I'm too cheap right now to buy an HD Tivo for Direct TV so this is my set-up for now. (I spent too much on my Outlaw gear!)
