By way of a post over at Gizmodo, by installing the latest software update for Vudu, you are given the option of being able to extend your rental for another 30 days or an extra 24-48 hours. Apparently Independent Titles on Vudu are rented for 48 hours. The extra cost is $2 off HD movies and $1 off SD movies. Is this a feature you would like to see implemented on Apple TV?
