Please forgive my lack of knowledge in this area, but here's the story- I wasn't planning on upgrading my current receiver for a while, but I got a great deal on a player that does DVD-Audio and SACD (through an analog 5.1 output) that was too good to pass up. Only problem is my current receiver doesn't have a 5.1 analog input, so I can't hook it up properly. If I do have to get a new receiver, I'd like it to be compatible with any known upcoming audio formats, so that at the very least I can hear them without having to replace it yet again. That said, I don't know much about the new audio formats on the new HD discs like Dolby TrueHD and what exactly you need to play those properly. I probably won't be getting either HD-DVD or Blu-Ray for a while longer, but if I get a new receiver now I basically don't want to have to worry about it missing something I need to connect and play those properly. When I bought into DVD, I bought a receiver with Dolby Digital and DTS (one of the first affordable ones that actually included both, for under $1000) because I refused to listen to 5.1 soundtracks downmixed to 2-channel on my old one. So, with that in mind, am I safe buying something that's out now or will it be obsolete fairly soon? I know HDMI is a must; I've also noticed the Blu-Ray and HD players currently out have 5.1 analog outputs on them too; will those output all sound formats that are in use or do you need a separate decoder for some of them? Basically I want to get something with analog 5.1 jacks so I can enjoy my SACD player now, and have it ready for the new video formats when I finally upgrade to those. If those new formats are going to require more than what's available right now, I'll just wait a little longer.
