Saw a copy of this item in Sunrise today. As previous reviewer noted, "Entire HBO series" is mentioned on the front and back of box. One disturbing piece of info is that the run time is listed on the back as "approx. 12 hr and 30 min". If this is correct, then the best we can expect is the 39 HBO episodes and not the remaining USA episodes. I hope the run time is incorrect.
UPDATE (HUGE DISAPPOINTMENT): Curiosity got the better of me, and I bought this set. Big mistake. Set consists of 6 discs with 5 episodes per disc (ie. 30 total). My guess is that "complete collection" consists of previously issued 3 volumes of 10 episodes each "best of" packages, but I don't have the energy to confirm this. If you are looking for 30 random episodes of this series, then this set is for you. Otherwise, I would give it a pass.
UPDATE #2: In response to Mike Deluca's querry, vendors receive product prior to release date and occasionally copies appear on local store shelves a few days before the official release date. This is how I secured my copy. Subsequent to my review, TVShowsOnDVD (an excellent website) received confirmation from Alliance regarding the 750 minute run time for this release (equivalent to 30 episodes).
