For hookups, I'd use HDMI direct out of the disk players into the Epson, assuming it has the required number of inputs.

Either coax or optical digital cables (one per unit) will do for the audio. Speaker cables to taste and you'll need a couple subwoofer cables of appropriate length depending on where you put them. 5 XLR M/F cables to connect the two Outlaw units as well as a 1/8 inch mono cable for the power amp trigger.

The DVR can probably use component video, as it won't be 1080P.

You should probably add a Harmony or Pronto remote to the system as it makes enjoying the system much easier.
