You can also use a digital coax cable (color orange) to go into coax 1 for DVD coax 2 for cable box. Just make sure to set the coax in input settings. The coax cables are a little cheaper than the optical cables and work just as well.

If your TV has an HDMI input, hook up the PS3 w/an
HDMI cable to the TV. This will give you a high def picture (set up the
PS3 to output the max resolution your TV displays). That will take care
of the video side.
Next hook up an optical cable from the PS3 to the receiver. In the PS3 menu, you have to change the audio settings to output the sound via the optical cable.
Finally to get sound out of the receiver to the speakers, you have to setup the receiver source input. For example if you setup the PS3 to play thru "VCR" input, then you have to make sure the VCR input is setup to use either optical 1 or optical 2 for sound (whichever one you have the optical cable plugged in from the PS3).

IT IS ALWAYS BEST TO CONNECT ANALOG AUDIO IN ADDITION TO THE OPTICAL, COAXIAL OR HDMI AUDIO CONNECTION. IF USING OPTICAL OR COAXIAL CONNECTIONS BE SURE TO CONFIGURE IT IN THE RECEIVERS DIGITAL ASSIGNMENT AREA IN SETUP.
ALSO, ON THE FRONT OF THE RECEIVER IS AN INPUT MODE BUTTON, PRESS THIS BUTTON UNTIL AUTO IS DISPLAYED

After days of frustration the real problem was with the cable box. It needed a firmware update. Following forum advice I disconnected the cable box power cord for a few minutes, reconnected it, allowed the cable box to reinitialize. Turned off receiver and TV. Turned TV back on and set it to HDMI connection, turned on receiver and all worked fine. Great picture and sound.( Needed to buy an optical cable to go from the cable box to the receiver to get sound from the speaker system. )--the dirtybird

I had the same problem. You're not doing anything wrong. the thing is you can't (I don't know why but the owner manual says it) have sound going to your tv AND your HT speakers when you're using HDMI. You should try going to input setup, choose hdmi audio out to your TV instead of the speakers, and then run an optical cable from your satellite to your receiver, assigning it to the TV/Cable input.
