If you can't wait to see episodes air on Bravo later this year, check out the fifth season of HBO's critically acclaimed Six Feet Under on DVD. The series takes a darkly comical look at members of a dysfunctional Pasadena, Calif., family that runs an independent funeral home. Also in stores this week: season one of Knots Landing, season three of Degrassi the Next Generation, and seasons four of Quantum Leap and Northern Exposure.
