New codecs worth making a switch right now?

Yes it is worth it. The improvement in sound quality is a quantum leap forward. Viewing cinema in the home with a good AV receiver and Blu Ray combo is mandatory Sat night entertainment for our family.

I just picked up the Talking Heads Stop Making Sense on Blu Ray. The sound playback is jaw dropping. I sat in the center seat with a smile from ear to ear from start to finish.

If yur Blu-ray player does the decoding internal and outputs PCM digital, then you don't need a new processor. Yes, the new HD audio formats are a major improvement over DD and DTS.

Prpixel- I don't believe all processors or receivers with HDMI from a year or two back are able to decode multichannel LPCM. I know that the McIntosh units are not able to do so.

It would be nice if we had a consolidated list of which units can and cannot decode multichannel LPCM (other than the newer units out in the last year).

Don't confuse LPCM with PCM. LPCM is the 7.1 channel high resolution output and can only be decoded by the new processors with DD-HD and DTS-HD codecs. In the audio setup of your Blu-ray player select PCM as the output for DD-HD and DTS-HD. This causes the Blu-ray player to decode the HD audio internally and down mix it to 5.1 PCM which any processor that has HDMI inputs and can process DD and DTS can decode. I've seen it done on many different Denon, Onkyo and Integra receivers. Also, I'm doing it on my own home on both Anthem AVM-20HD and Statement D2 processors using Panasonic Blu-ray players

Here's a link to the official Dolby Labs explanation.
