Best Corrs DVD


I am looking to add a Corrs DVD to my music concert collection. Which do you consider the best in terms of sound quality (2ch only) and having a good selection of their more celtic songs/instrumentals? I do not have any processors, etc - just a straight 2ch system. Thanks for any suggestions.
