Ok so I'm looking at getting the Sony STR-DG810. I've read that it passes dd+ and LPCM which since the ps3 can decode thats means I'll get the hd sound through my 5.1 with this reciever right? But what about my a20 and a3 which say they decode pcm and not LPCM?

You'll be fine because in this context PCM and LPCM are the same thing. Here's a quote from Wiki:

Linear pulse code modulation (LPCM) is a method of encoding audio information digitally. The term also refers collectively to formats using this method of encoding. The term PCM, though strictly more general, is often used to describe data encoded as LPCM.
