There is a Dolby test disk available as a torrent download. It's got all the test tones, 5.1 speaker setup tones, various 5.1 designated audio to test a HT setup.

Be careful with the low frequency sweeps as they go very low (10Hz) and can kill an average smaller diameter driver (speaker).

From the above images I'd suggest you'll only get 5.1 from a DVD playback and perhaps a 5.1 recreation from stereo input assuming the audio stream is encoded correctly.
