Ok so my RX-V3800 can decode dolby true hd..... the sony BDP-S500 can output it.... but I've got a fiber optic cable for sound connecting the two. Is this the problem? Do I HAVE to run the hdmi from the bluray TO the receiver and then one out from the receiver to my TV?

But then it says my player can decode internally and then just send it through the fiber optic cable. Is this truHD anymore?

The trueHD light on my receiver isn't lighting up so something's no go here.... please help a lost soul. Thanks!
