More and more TV on DVD is being released, and the DVDTalk review panel is committed to covering as many sets as they can. Check out these highly rated releases:  Parker Lewis Can't Lose: The Complete First Season - this is a must watch, and is likely to appeal to anyone who enjoys a silly, over-the-top good time; Mystery Science Theater 3000: XV - these four 'experiments' are as fresh, fast-paced, and hilariously funny as they were in their original airings; and Sergeant Preston of the Yukon: Complete Season 2 - just as primitively exciting and heroic as the first season. Other shows recently reviewed include:  John Adams (Blu-ray), Hawaii Five-O - The Sixth Season and Everwood: The Complete Second Season.  Want more?  Check out all of the TV on DVD reviews in the DVDTalk database.
