Andy Griffith is wily defense attorney Ben Matlock in the final season of "Matlock," now on DVD.

The last season of “Matlock” leads a potpourri of TV shows arriving on DVD this week.

“Matlock: The Ninth and Final Season” (CBS/Paramount, 1994-95, five discs, $54.99, 15 episodes, teasers). Between the first season and the last, this venerable series (still popular in reruns) had seen a complete change in the supporting cast. But that never mattered, since Andy Griffith as wily Southern attorney Ben Matlock was always the draw. Who even remembers the supporting players?

This is soft, somewhat bland comfort-food television. Though this season initially aired in the mid-1990s it could easily pass as late-’70s or early ’80s fare, but Griffith remains a pleasure to watch, whether investigating the cases himself or standing up to prosecutors and witnesses in the courtroom. Fans will be more than happy to complete their collections with this final edition.

“Orphan Black: Season one” (BBC, 2013, three discs, $29.98, 10 episodes, featurettes). Offbeat, gritty Canadian sci-fi series stars Tatiana Maslany as Sarah, a British con artist in America who stumbles upon a woman that seems to be her carbon copy and watches as she commits suicide. Assuming the dead woman’s identity to steal her money seems like a cinch, until she becomes too wrapped up in the woman’s life, discovering she was a police detective under investigation for shooting an innocent civilian. Then she finds the cop was her clone, and there are other clones out there, and someone is trying to kill them.

Engaging mystery-thriller benefits greatly from Maslany’s ability to play a variety of characters quite convincingly. The show has been renewed for a second season on BBC America in 2014. (Also on Blu-ray, $34.98)

“Hell on Wheels: The Complete Second Season” (eOne, 2012, three discs, $39.98, 10 episodes, featurettes). This AMC cable show is a dark, brooding Western set against the westward expansion of the first transcontinental railroad. The lead character is a former Civil War soldier (Anson Mount) looking to exact revenge on the Union soldiers that killed his wife, with an uneasy ally in a former slave, a railroad worker played by Common. This season, the Sioux rise up against the “iron horse” and Colm Meaney, as the corrupt construction boss, gets his comeuppance. (Also on Blu-ray, $49.98)

“George Lopez: The Complete 3rd Season” (Warner, 2003-04, three discs, $29.98, 28 episodes).
