OP in that thread said exactly what you believe, most others that joined in share my beleifs............
And I'm not comparing dick sizes BXT, you simply said "if your home theatre gear is basic" to which I assured you it is not! I could also find various $2 articles on the subject. Like most things on TeH InTeRnEtZ there are fors and againsts for any topic you care to name. The trick is to seek out industry professionals and the like and find out first hand what shit sticks to the wall when thrown!!! Experts > Salesmen
Anyway sooooo off topic, Fred's buying a PS3 and has HDMI cables already, I'm ultra happy with my theatre as are you with yours. Situation sorted!
