Yes. And you must wire them in stereo and not dual mono. The encoding of DVD will not be improved, but music will be far better that way. Just because someone has not learned critical listening skills a producer of music would know does not mean your ears and brain haven't noticed.
Thanks for the confirmation. Will it make any difference for when I'm listening for music if I have a setup of 2.2 rather than just 2? I guess having a 5.2 setup for movie watching is enough if the player used for movies and music is the same.
