Help please

I'm not sure if this is the correct thread, but please move if it isn't. I have a Pioneer DV545 player and a Pioneer VSX-D811S-S Amp. My problem is, is that when I play a movie with DTS the DTS logo does not appear on either the Amp or The player. I have set DTS to on in the DVD players set up. I am not overly bothered about the symbol displaying but what I am wondering is am I getting DTS output on DTS movies?

Thanks for any help

P.S I am using a digital coax to connect the player and the Amp.

Sounds like you aren't selecting the DTS soundtrack from the available ones.
