DVD Playback Modes
Using 4 channel surround speakers your Seismic Edge
 sound card
can deliver true multi-channel surround sound from a compatible
soft-DVD player application even if the player only supports stereo
output. If the soft-DVD player is capable of providing a true 4 chan-
nel Dolby Digital  downmix Seismic Edge will output 4 channels.
Even if the soft-DVD player supports 4 channel Dolby Digital  you
may prefer using QMSS  playback of DVD's because of the
enhanced rear channel content it provides. If you have only stereo
speakers Seismic Edge can also provide virtual surround using it's
2D to 3D remapping feature.
To enable 4 speaker QMSS

DVD enhancement:
1) Make sure ''4 Speakers'' is selected in the Seismic Edge control
panel settings tab.
2) Open the ''control panel'' or settings menu for the soft-DVD
player.
3) Select the menu or tab that controls the player's audio settings.
4) Look for a panel that allows you to select the number and type
audio channels
5) Select either 2 speaker ''Stereo'' or 2 speaker ''Dolby Surround
or ProLogic'' Either option will work well as the QMSS

DSP
algorithm does not depend on Dolby encoding. (Effectively you
should follow the soft-DVD player instructions for playing back
over stereo speakers even though you have quad speakers
connected).
6) Close the control panel and play a DVD. Seismic Edge will
detect that it is in 4 speaker mode but is only receiving two
channels of audio from the DVD and automatically generate 4
distinct channels of surround sound using QMSS
