Some great TV shows have made their way onto DVD this week including:  Little Britain: The Complete Collection - With a blend of surreal humor, eerily evocative roleplaying, and searing sense of humor, this is one of the most socially devastating TV shows in recent memory; Lost - The Complete Third Season - taken as a whole, and without the enforced breaks in continuity the show suffered during its broadcast run, the third season of Lost is arguably its finest yet; Roots - The Complete Collection - one of the epochal television events of the 20th century, this miniseries created a cultural ripple which many would argue continues to this day.  Other shows include:  Frasier - The Tenth Season, McLeod's Daughters - Season 4, Gomer Pyle U.S.M.C. - The Third Season, Will and Grace: Season Seven, Bill Maher - The Decider, and The Wiggles - Getting Strong.  Want more?  Check out all of the TV on DVD reviews in the DVDTalk database.
