Recently I've watched a couple of movies and noticed the output from my sub (JBL PB12 w/ PE Dayton amp replacement) is lackluster. I generally watch DVDs with my Onkyo receiver set to "direct", which I'm thinking means it doesn't do any processing to the signal as it comes from the DVD player. Once I swithc over to another input (TV, CD, etc) the sub is it's old self. I'm making sure I select DD5.1 on the DVD player (Samsung) movie menu (connected to receiver via digital coax). I can switch the processing on the Onkyo to something other than direct (DPLII or DTS:Neo or other) and the sub comes to life. The two movies in question are the new Transformers and the new Star Trek...so my question is - are these two movies just not a "hot" soundtrack, or have I(or the wife) changed something on my receiver and don't know it? In "direct" mode, the receiver shows PCM, rather than DD or whatever...is this the way it should be?
