Love is in the air this week on DVD -- in all its weird permutations. First you have Ben Stiller as 'Greenberg,' a fortysomething lost soul looking for love and meaning and finding it in a most unusual place. 'Chloe' ratchets up love (and lovemaking) by throwing a wrench into a seemingly happy family in the form of an escort to test marital fidelity. Next there's 'Our Family Wedding,' a comedy that pits an African-American family against a Mexican-American family when their kids decide to get married. And lastly there's the love-hate relationship of 'The Bounty Hunter,' which pits ex-marrieds Gerard Butler and Jennifer Aniston against each other in a comedy about (you guessed it) a bounty hunter who has to track down his ex-wife.
