Forum Members - This is my first post and I am NOT an expert in any area of Home Theater, Audio, equipment etc., so please bear with me. I stumbled across this site a few weeks ago and have been simply overwhelmed by the knowledge and expertise of the forum members, as well as the daunting COMPLEXITY of the subject. I am a recent retiree wanting to build an entertainment center upstairs for my family (including a 10 year old little boy) and a recommended receiver from several sites on the web is the Denon AVR-4306. However, a CNET article states "Expensive; intimidating complexity may put off home-theater newbies; no built-in decoding for next-gen HD-DVD and Blu-ray audio formats; no HD Radio." I'm not concerned about the complexity (though I probably should be), but I am concerned about the "no built-in decoding for HD-DVD etc. What does this mean and how does it restrict my future viewing of high def movies? I simply have no clue and don't know anyone else to ask. Thanks in advance and I'd be very grateful for any responses.
