about 85% of ps2 games are usually just in stereo. However I have a 7.1 surround sound system and usually ouput theses games and anything else thats just stereo to either DPLII or Neo6 (which of these two formats is better anyway?) and it plays the sound through all seven speakers rather than just the front left and right. Does this help with non surround sound games? Like what does it play through the rest of the speakers? like are the left side speakers acting as the left front speaker and right side speakers acting as the front right speaker? or do the rest just play in all the sounds from both the left and right front speakers? Do you guys set it to DPLII or Neo6 on non surround sound games as well?
