THE following movies are now available on DVD and/or video:

 "The Motorcycle Diaries" - This exhilarating portrait of the young Ernesto "Che" Guevara in his pre-revolutionary days was one of the finest films of 2004. Gael Garcia Bernal stars as Guevara, an idealistic medical student, who embarks with buddy Alberto Granado (Rodrigo de la Serna) on a rowdy road trip throughout South America aboard a battered motorcycle. In a brief conversation on the DVD, the real Granado looks back on the trip 50 years earlier and notes how events depicted in the film, including a stay at a leper colony, sowed the seeds of Che’s rebellious humanism: "His farewell to the lepers seemed to say, ’I am leaving this common medicine to become a doctor of souls, of the people,’" Granado says. The disc also has two Spanish television segments on Bernal and three substantive deleted sequences. DVD, $29.98. (Universal)

 "Saw" - The low-budget exercise in sadism became a $50 million hit with the horror crowd and has a quickie sequel in the works for this fall, just a year after release of the original. The players: a doctor (Cary Elwes) and a photographer (co-screenwriter Leigh Whannell), who awaken chained in a dank basement bathroom with a bloody corpses between them. The game: a serial killer’s twisted test of their moral fiber as each man is informed he must kill the other or suffer horrific consequences. Whannell and director and co-writer James Wan collaborate on commentary. The DVD also offers a background featurette, two music videos, a making-of segment on one of the videos and a collection of the movie’s advertising images. DVD, $27.98. (Lions Gate)

 "Taxi" - Queen Latifah’s a sassy cabbie and Jimmy Fallon’s an inept undercover cop in this forgettable buddy comedy that teams them up for a series of high-speed chases throughout Manhattan on the high heels of gorgeous female bank robbers (led by model Gisele Bundchen). Thankfully, Ann-Margret’s on hand to provide a few chuckles as Fallon’s boozy mother. Along with the theatrical cut, the DVD features an extended version that adds a few minutes of footage.

The DVD also has four deleted scenes and a batch of background featurettes, including a Comedy Central segment with Latifah and Fallon cruising New York in a cab. DVD, $29.98. (20th Century Fox)
