I am afraid that I am the bearer of bad news. You have chosen poorly. The 2500 is a transport and will not decode DTS HD Master or Dolby true HD. In addition, your AVR4306 lacks these codecs as well. Thus, no matter what combination of settings you pick, you cannot get what you are asking for. If either of these devices is new (probably the BluRay player because the AVR is an older model), consider returning it immediately and getting a compatible device.
Sorry.
