Advice from Jerry
I am glad you posted this on the forum....
Since you already have your HDTV - I think speakers represent the area of of most improvment. HDMI is great but you need HDMI sources such as HD DVD and Blu-ray. I recomend you get both as well as a Netflix account so you can try HD movies before you buy them for your permenant collection.
Another cool element I always recomend is a Harmony romote. KennyT LOVES them and I do to because they are easy to program, cheap and fun to use.
