That's good. You know that is not the problem. You also stated that you could hear them fine with DVD movies right?
I'll check my own receiver (I have the 601 when I get home), but that won't be until 7:30PM PST.
BigJohn might be able to help you out sooner though.
How do you have the DVD Player hooked up to the receiver? Digital? RCA connectors?
What type of music media are you listening too? CD, DVDA, SACD?
Is it possible that the cables you need for surround left and surround right are not plugged in or not plugged in properly (for music)?
Is there a setting on the DVD that you need to check to set which connection to the receiver to use for different types of music/video?
