Micco, another welcome. You didn't specifically name the Rieu DVD in question and as Jack mentioned you should examine it carefully to see if it in fact has a DD 5.1 soundtrack. Also, even if it does and your player is set correctly, keep in mind that many classical DVDs(don't know about Rieu's)aren't intended to have "awesome" sound coming out of the surrounds. Rather than placing musicians discretely in the surround channels the surround content is simply general ambience from reflected sound, which is a relatively subtle effect which doesn't draw attention to itself.
