LFE output from DVD player's subwoofer out

I am using an ATI 1506 amplifier with a Blue Circle 21.1 preamp. For surround sound processing, I am using an EFE Technologies PRO ONE passive surround sound processor. With my current setup, movies sound very good, but lack the Low Frequency Effects (LFE) that could really take it to a higher level. I've begun searching for a progressive scan dvd player that has onboard decoding of DD/DTS. Some of the newer multi-format players have an output for a subwoofer. My question is this: Does the LFE information (assuming the dvd in question has an LFE track) get sent to the subwoofer out connection onboard the dvd player?
Any assistance you can provide will be greatly appreciated!

Thanks,
