Tips for Dealing With Commentary Audio Problem

Watch it on a DVD-enabled computer w/headphones, making sure that the DVD player volume is at full blast, as well as the computer itself. This seems to fix almost all of the problems I have with faulty DVD audio, especially since I have a pair of those big studio headphones. Not only do I hear the main audio loud and clear, I also hear the background audio that's impossible to hear with normal TV speakers.
