Magical VHS tape improves a guys love life

Its not a mainstream movie. A guys is down on his luck and somehow borrows a magic vhs tape from this weird couple. The tape gets him into several situations including a yoga instructor and a pair of salesgirls in a store changing room, each teaching him and making him a better lover. He meets a recovering sex addict and falls in love. At the end of the movie he returns the tape late, which results in all he learned being lost and all he did erased so he gets a chance to try again with the girl he fell for.
