I'm not sure how I missed this post from a couple days ago, but I certainly did... oops...
So we are using the analog subwoofer output from the DVD player (connected directly to the subwoofer) and the digital audio output from the DVD player (connected to a receiver or pre/pro). Since there is an analog subwoofer output available on the player, then it must have at least an onboard Dolby Digital decoder (possible DD and DTS decoders if it's a somewhat newer player -- my Panasonic RA60 has both onboard, and I think most or all players in production today that have onboard DD decoders handle DTS as well). From what I've seen, unless you disable something in the player's setup, all of the available signal paths are active at once: the stereo analog outputs, the digital audio output(s), and the 5.1 analog outputs. The only case I can think of where this wouldn't be true is some players that ship with the DTS digital output disabled (including both of my Pannys).
So if we have all of the outputs active, then the LFE signal would be in the digital output
and the analog output. The analog LFE out would also be carrying any redirected bass from other channels, assuming the player's DD/DTS decoder includes bass management (which they seem to all do, by way of large/small speaker settings and a fixed crossover that is probably set to 80Hz but I suppose could be 100Hz on some players) and you had configured it with any speakers set to small. This should hold true for any player with an onboard decoder, as far as I know.
I don't have any DTS CD's to experiment with, but if the player has a DTS decoder I would hope that the player would recognize the signal from a 5.1 DTS CD and automatically run it through the DTS decoder while also providing the digital audio output. Obviously, if there's no DTS decoder, we're out of luck.
