Virgin Media's UI also brings a lot more information to the fore, with detailed programme info. Also worth a look is the series link page, which allows you to not have to worry about forgetting to record each week.
It's not a groundbreaking new feature, but the way it's been packaged up is slick and will help make sure you don't miss the shows you've been looking forward to for months.
