Default Some real basic Bluray audio questions....

I dotn want to sound like a newb here but I'm hoping somone can help me out.
First of all my equipment...

Onkyo TX-SR602 Home theater amp 7.1 (about 3 years old i think)
Playstation 3 Blu ray Player
Sony 46" bravia e3000 full 1080P Lcd TV(Brand new)

hook ups.
Ps3>>TV....HdMi
PS3>>>ONkyo tolslink optical cable

Now here are my questions.
What kind of audio can I receve with this setup?
When I watch movies it says Dolby Digital on my amp and I am getting S.S.
Am I capabkle of listing to "DTS TrueHD" or the other new 7.1 lossless audio formats?

I am kind of lost here but from what I gather using an optical cable is not the best way to go anymore?
Getting an amp with HDMI is now the "best" way of doing things?
Any help would be great
Thanks in dvance

You can only get the lossless audio via HDMI to your receiver. True HD etc..

The DD you see is more than likely just Dolby Digital 5.1.

Thanks, great article.
So really all I am getting right now is just audio that gets downsampled into plain old Dobly Digital or DTS same as my old DVD's I guess.

One question that never got answered is... the new recievers out there,do they need to have these decoders built in them or are all these formats still decoded by the basic Dolby Digital and DTS decoders?

Thanks again.

The new codecs require new decoders. The decoders can be either in the player or in the receiver.

You can get Dolby Digital, and DTS only. When you play a DTS HD MA soundtrack it extracts the core which is at 1.5Mbps. When you play TrueHD you get the DolbyDigital Core @ 640Kbps. If you select PCM you get 2channel.

In the case of the PS3, it can decode TrueHD internally and output that audio track as a PCM to your receiver. You do not need a decoder in your receiver to hear the full lossless TrueHD track. On the DTS HD MA tracks you can't yet take advantage of then fully via the PS3. Sony and DTS insist that the PS3 can decode the DTS HD MA into a PCM and output it directly to the receiver, but Sony won't release that firmware update as of yet. Presumably they are waiting for a player with profile v2.0 and internal DTS HD MA decoding support before they release the update for the PS3. This is to avoid angering their partners who would like people to invest in their stand alone player rather than the PS3.

The PS3 cannot bitstream any of the HD audio codecs to your receiver to be decoded. It can only decode it and send the PCM.
