Interested in renting TV episodes on your iPad running the shiny new iOS 4.2? If you're in the US, you're in luck. While not all TV networks are on board yet there's still a decent amount of programming and the ability to download it and watch it offline if you're going on a road trip or flying cross country is very convenient. Find out how after the break!

You can now rent TV episodes directly on your iPad for just 99¢ each. Use iTunes and simply tap a show's View button to see the Buy and Rent options. Tap Rent to start the download and the rental clock -- 30 days to start watching and 48 hours to finish once you start. Use the Video app to view downloaded episodes. And if you've upgraded your iPad to iOS 4.2.1 you can use AirPlay to stream episodes directly to other screens on the same wireless network via Apple TV.

Hopefully more networks (and more countries!) will support the service soon. If you've used it, let us know how it worked for you, and if you prefer getting your TV from somewhere other than iTunes rentals, let us know where!

Bonus tip: TV rentals also work on iPhone and iPod touch.
