I just had Fios installed in my home and had them install a couple of Mot. QIP6200's. I'm using Toslink out to my receiver which is detecting a good link, however there is a serious lack of LFE from the signal. Is there some tweak or change required to get this sounding properly? If I hook the same cable to my Oppo DVD player or my old DirecTV box via the same Toslink the LFE is "normal".

Help! I'm at a loss and know very little about these boxes.
