PS3 Blu-ray to surround

[stephmoreland]

I just bought an LG 42" TV (42LH30) that came with an LG home theatre system (HT963TA) and I have my PS3 that I watch Blu-Ray on.
I want to know how do I, if it's possible, use the HT963TA for surround sound while watching the Blu-Ray movie, or is this just not possible?

If the HT setup doesn't have HDMI, then you will have to use optical. You won't be able to get the latest audio formats, but you will get surround.

I looked up the manual and it appears that unit has hdmi out only, however it does have an optical in so as j_garcia stated you will have to run an opt cable from your PS3 to the HT unit.

The HD audio needs to be decoded and it really does not matter where this step happens. It can be done in the PS3 or in an outboard decoader (AVR or dedicated audio unit) before it can be converted to analog and then amplified.

Yup! Use the optical connection. You will need to go into the PS3 settings and make sure you are sending PCM and not Bitstream to the HT box.

For optical, I believe you want it set to bitstream for the new codecs to work properly (in their reduced fashion). With HDMI to a compatible receiver, you want PCM.

I am not sure the LG box decodes the HD formats... if yes, then yes.

With HDMI to a compatible receiver, you want PCM.

If by compatible you mean HD format decoding capable, the cannot he send bitstream over HDMI also?

The PS3 will decode the new formats however my understanding is that optical doesn't have the bandwidth to handle uncompressed 5.1 via PCM. 2.0 uncompressed only. Bitstream is compressed and can carry DD5.1 and DTS over optical. HDMI can carry up to 8 channels uncompressed which is why you want to use PCM if using HDMI.

You won't be able to get the new formats either way with your setup but you can at least get DD or DTS.

I could be mistaken but that's how I understand it to be.

DTS-HD will pass it's "core" 5.1 and Dolby TrueHD tracks generally also have the ablility to do this as well over SPDIF, though someone here said there is actually a separate track that has to be present for the TrueHD to work correctly. I am using bitstream over optical and I am able to select TrueHD and DTS-HD in 5.1.
