[Blu-ray] TruHD and DTS Master on non-TruHD or DTS master receivers

Hello, I have a question about audio on Blu-rays. I bought a Resident Evil: Extinction. I haven't opened it yet but I'm worried about the audio specs on the back. Under audio, the disk states the following:
English, French Dolby TruHD 5.1, Portuguese, Spanish 5.1 (Dolby Digital.

I started going over other new Blu-ray releases and see that their audio specs state they play either English 7.1 DTS-HD Master or TruHD 5.1.

Given that my audio receiver does not have codecs for DTS Master or TruHD 5.1 and that my Panasonic DMP-BD30 blu-ray player does not have internal decoders, will my receiver play these discs through my 5.1 channel system? Will these discs plays as normal Dobly Digital and DTS even though it doesn't say so on the back of the box?

Sony has recently been releasing movies with a DD5.1 "hidden" track tied to the TrueHD menu item. So if you select TrueHD in the menu and your output doesn't support it, then it reverts to DD5.1.

Hope that helps.
My understanding is that you should be fine. The Tru-HD should include a hidden DD core that your player and receiver will be able to handle. DTS-MA has a standard DTS core that will do the same.
Just as an aside, some of these "old" codecs actually sound pretty darn good on HDM. Not as good as the lossless, of course, but they beat the pants off of what I'm used to from DVD.

At least that's been my experience, anyway.
Well, my audio receiver doesn't take audio through the HDMI. It only passes audio and video to the TV. It does accept audio through digital optical and digital coaxial.

As for "old" codecs, this the first time I've ever had a 5.1 sound system so it all sounds pretty impressive to me.
