Yes, but no.
For audio, you are correct, you could just connect optical to your A/V receiver and you will get 5.1 from the ATV or any other source which supports digital audio output separately from the video, such as your cable box, or the PS4.
But, you can't use adapter cables to get from HDMI to analog. That is, HDMI is 100% digital, if your final connection is component video, composite video, s-video, or VGA, then those are all analog video connections, and the only way to make that connection to a HDMI device is to use a active HDMI to analog video converter, and one of the only ones out there is the HD Fury. It's about the dumbest thing in the world that HDMI and product manufacturers have done really in eliminating component video connections and worse that there aren't a ton of cheap HDCP strippers out on the market that do a decent job doing what the HD Fury does. If you were outside the USA, there are some cheaper alternatives.
But, what kind of projector do you have? Have you tested different DVI cables to it? Have you used shorter cables? Have you considered that it may be time to upgrade the projector?
It is best practice, as mentioned above, to simply run HDMI from all your sources to the A/V receiver. Then from the HDMI output of your A/V receiver run into the HD Fury, then from the output of the HD Fury, you would run component video to the projector. But, I don't know what kind of A/V receiver you have beyond 'Yamaha'. It's like saying "I have a Chevy, how do I make it hit 180 miles per hour?" Need an actual make and model of everything for best responses.
