"Movie6 MHR" means that the player is decoding the Dolby Digital (or DTS) stream and sending it, multichannel, to the G68 with MHR encryption.

You get "DTS 3/2.1" or "AC3 3/2.1" on the G68 from laserdisc because the laserdisc player does not decode the bitstream internally. The G68 gets the bitstream and decodes it for your listening pleasure.

The particular display on the G68 you mention is telling you the audio format that is arriving at the G68, after any decoding that has happened upstream in the player. Worry not, you are listening to full six channel audio decoded from the Dolby Digital stream on the disc. The fact that it is decoded in the player and delivered to the G68 already in multichannel frees up DSP power in the G68 to do snazzy things like upsampling.

Oooh, forgot to mention. If the player is delivering a 2 channel downmix to the G68, the G68 will report "Movie2" on this display, ie. it's a Movie preset and there are 2 channels of audio on the input wires.
