Ran 7 DVD-A disc through the player, HDMI set to bitstream, and also set digital audio to bitstream although dhould not be a factor here. All discs were recognized, loaded and played fine, however, all signals were passed as PCM and identified as such on my SC37. I through a DTS disc in, and it was recognized as DTS. The only other oddity, was on some DVD-A discs, on certain tracks, the image on the screen would not render, but just for a specific track. Discs used in the test; Fleetwood Mac Rumours, Say You Will; Eagles Hotel California; Chicago Chicago V; Doors LA Woman; ELP Brain Salad Surgery; The Band Music From Big Pink; Steely Dan Gaucho (DTS). One last thing. The Band and ELP playback, were a bit different. Listening to the Weight, the primary/lead vocal was produced out the left channel, ELP lead vocal was equal between left and right, stereo if you will (5.1 was still being produced), not center centric. However, without knowing how these were mixed and the intent, it is difficult to say whether or not this is correct.
