Yet another dvd set that will have exclusive retailer content... Currently BestBuy is listing an exclusive bonus disc offering, a Q&A from the Museum of Television and Radio's 2006 William S. Paley Television Festival. http://www.bestbuy.com/site/olspage....cat97500050035 Who knows what the other retailers might or might not offer? I was planning on pre-ordering this from AMAZON! This habitual habit of offering these exclusive discs is really killing my ability to pre-order anything. You can't pre-order it from bb.com because they don't include the bonus disc even though they somewhat imply that you'll get it. Ridiculous. This should have been included on the set.
