Well, yes and no. We are talking about a Tomita Planets DVD. It has a movie of our Solar System that runs with it.
The DVD only says stereo, the packaging list Dolby Surround. It is DEFINITELY discrete. I've just never experienced this behavior out of my gear before. It switches to PLII even when I set the receiver to Direct (where I leave it for surround stuff - I just want the bits off the disc, no gimmicks).
Got it! :upthumb
Are there any soundtrack options (e.g. Surround.. Stereo) when you hit the "Audio" button on the remote control of your DVD player while the disc is spinning..?
