Have downloaded that pdf file which was linked through a previous thread which adds to the explanation and help you have provided.

Based on what I am learning...

a Question regarding ver 1.3:

Let us say we have a 1.3 amp along with the PS3 which is 1.3.
Let us say for argument's sake that the PJ is 1.2.

Therefore if I plug the PS3 into amp with HDMI and then HDMI to projector but have optical running also from PS3 to amp, would this enable 1.3 for audio but keeping 1.2 for picture or would the PJ cancel all out and relegate all to 1.2 thereby negating any need to wait for 1.3?

further to:

So, if I only have one output source of HDMI (i.e. the PS3) and connect it to the PJ for Hi Def image.

Would there be no difference in terms of sound if that is fed into the Amp via an Optical rather than HDMI?

Therefore if with only one HDMI source and the current absence of ver 1.3 I wouldn't get any difference in sound with either an amp that had HDMI sockets and one that didn't.

Would I still get uncompressed PCM via an optical cable or is that where the catch is? You have to have an amp with HDMI in order to hear that soundtrack... and hence why there is an argument that uncompressed PCM is so good, what difference is version 1.3 going to bring with HD audio when it is pretty amazing with this new enhancement. Is that it?

Am I learning correctly here?
