I know absolutely nothing about choosing a home theater but I am looking. I have done a lot of research on-line and have narrowed it down to one. I would like someone with a lot of knowledge to tell me if this is a good choice and answer one question for me about this unit. I hope I can explain the only drawback I found out about this unit from some reviews. It is: ONKYO HTSR 800. Several of the reviews have said that this unit has only one drawback and that is the audio does not go through hmdi, or whatever those initials are. Can someone please explain what this means and if I buy this set-up, would I ever know that there is something missing? Thank you so much in advance, pkla
