Question about DTS on Integra DTR 8.2


I'm a beginner trying to get my first setup finished. I recently purchased an Integra DTR 8.2 receiver, and now have my Millenium DTS Decoder sitting unused on my rack. Do you think the Millenium decoder would work better than the one built into my Integra receiver. Also another quick questions, my Yamaha DVD-C920 has a built in dts decoder, as does my Integra DTR 8.2 How does the system decide which DTS Decoder to use? and which one of the three would be best?

The DTS is decoded by the DVD player, and accepted by the DTS compatable Reciever, it is not that both decode it, it is the fact that both will produce it.
The receiver detects a DTS encoded source and decodes it. So if you have a receiver and DVD player with analog multi-channel inputs/outputs you can choose to have the DVD decode the DTS bitstream (send it analog to the receiver and have the receiver play throu the SACD or 7.1 input), or have the receiver get the digital signal and then decode the bitstream.
