Well that makes 3 of us big Neil fans on this forum. I really laughed when i read Doug's comment: "I'm going to wait til the archives are in my hand before I buy a Blu-Ray Player." How true.
There are really 2 key things to look for in a blu-ray player for the Neil Young Archives.
1) You want to be sure your player can decode the new HD audio formats. If the player can send the signals to your receiver in digital format (and your receiver can decode them), even better. A minimum is for the player to be able to decode the new HD audio formats and send the signal out 5.1 analog RCA connectors on the back of the player. You really need to get a player that can decode these HD audio formats to get the most out of the archives. They will be high resolution digital audio. The formats I'm talking about are Dolby Digital True HD and DTS HD Master Audio.
2) Get a Profile 2 player. Blu-ray players come in 3 flavors, Profile 1.0, Profile 1.1 and Profile 2.0. The archives will use the ability of the Profile 2.0 player to retrieve updates/additions to the musical/video material off the internet and store them alongside the original archive material. I'm not sure if this storage will be on the blu-ray disk itself or on the hard drive of the blu-ray player. I'm guessing on the hard drive.
I haven't done the research yet as to what players meet my requirements, so I cannot recommend any yet. Hope this helps you get the most out of the archives! I currently have the Sony BDP-S300 Blu-ray player. This is an entry level Profile 1.0 player that I got relatively cheap. My plan is to use it until I have to get a Profile 2.0 player (when the archives comes out is the most likely soonest)
