I realize this is a very old thread, but I was reading here hoping to find the audio supplements for the book 'Irish On Your Own'. Links I tried from this thread were outdated by now, but I have found a wonderful resource for this series at
http://ultach.org/ (link to Note You're Talking on the left)- including full video of each NYT episode, downloadable files of each accompanying chapter from the IoYO book, as well as downloadable files of the answers for each chapter and audio files for reading along with the book. I haven't tested all the links, but it appears to all be there!
