Does a 'test' dvd to test different flavours of coding exist?

[Edmonite]

I have a high end processor (Integra DTC 9.8), and have been looking to find a dvd that would allow me to select chapters coded in different audio formats - eg Dolby TrueHD or DTS-HD Master Audio to see the differences. Does such a thing exist?

Thanks in advance ... Edmonite

Though geared mainly toward video, it also includes trueHD and dtsHD tracks to test with.
