I have mine configured the same way but only using 2-channel analog audio. The 3803 will remember the speaker configuration per the processing mode.
If you have the DD/DTS working as desired, do not change it. Simply put the unit into Analog mode, then select direct/pure direct. Next, press the enter button on the remote, this will enable you to modify the speaker settings for whatever speakers are enabled. Keep pressing enter until the subwoofer is selected, then press the left arrow all the way until it reads "OFF". This off condition will only be in the analog/direct mode. Now when you switch back to DD/DTS/DPL2, the sub will be enabled.
I did this and it may be purely subjective or maybe my sub/RL were cancelling each other out, but at this point but it seems that the L/R speakes actually have more bass now.
