So I'm stuck with my SR600 which doesn't have HDMI. The only thing I can do is option 1 with analog cables, correct? And for this option, I need to player to do TrueHD or DTS-HS:MA and the player needs to have the analog connections to connect it to the receiver. Since the PS3 and the PS3 slim don't have analog, I'm stuck. I either need a Blu Ray that has these or a new receiver.

Do I have this straight now?

The only advantage to 3 over 2 is the receiver is decoding instead of the player, correct? It's preferable to have the receiver do this if you can choose between the two I assume.
