Volume Leveler might have some value in normalizing unruly program levels on TV, like commercials or across different channels. Depends on your TV provider. It does this by reducing dynamic range, so you'd not be wanting this for movies unless you're listening at extremely low volumes.
I don't have the ADA, so maybe your implementation of Dolby Volume Modeler includes an effective level offset control to calibrate its effect. My SSP-800 has no such control, rendering it totally useless. If the ADA is similarly lacking such a control, then yes, it makes sense to leave Modeler off.
Regarding above discussion regarding surround format, I prefer Discrete/Direct 7.1, Discrete ES/EX, Discrete THX, Discrete ES/EX THX, PLIIx in that order on Blu ray movies > even though rears may be mono, but in my setup I find the sound to be appreciably more clear/intelligible/ crisp in Disrete and Direct modes.
I suspect you are letting the term "discrete" influence your opinion. If you are playing a 5.1 soundtrack from lossless source (HDMA or TrueHD), Discrete ES/EX is no more discrete or clear/intelligible/crisp than PLIIx as none of these processes touch the L/C/R channels. If it is, there's something amiss.
THX presumably adds Re-EQ, which will remove a wee bit of top end sparkle, and if the ADA lets you turn off Re-EQ, then it becomes the same as the other modes in doing nothing to the L/C/R signals.
You can verify all this by muting the surrounds while checking the modes.
