Can we load video onto iPad without iTunes?

You can use the "File Sharing" feature of various apps THROUGH iTunes, but without having to actually SYNC with iTunes.

Install the free CineXPlayer app. This will allow you to play a much broader range of videos.

Then plug your ipad into any computer with iTunes installed. iTunes will recognize the device, and let you browse it WITHOUT syncing it. If you go to the "Apps" tab inside the device's pages in iTunes, you'll see CineXPlayer listed below, in "File Sharing". Select CineXPlayer and drag movies to the "Documents" pane.

Ta da!

• Use a free cross-platform program like Handbrake to convert your video into an iPad supported format
• Take an SD card that you've used with a digital camera and put your movie(s) into the DCIM folder
• Use the camera connection kit to load the movie. For all the iPad knows, it's a movie you shot with your digital camera
• Note that the movie will load into your "Photos" and not your "Videos" - that means there are some limitations (no recognition of chapters, no resume functionality) but it will work very well and is a much easier solution than anything that uses a connection to a computer or to the cloud

"Instead of syncing have you tried the Manually Manage option? Then you can load content to it from multiple PCs without doing a complete sync. support.apple.com/kb/ht1535 – Ryan Sharp Jan 25 at 16:55"

Contrary to this being the top rated answer, this is incorrect. In order to actually choose the Manually Manage option, you must first sync the device with that target computer. I just tried it and it tells me that it will erase all content on the iPad and then I will be able to manually manage. This is a DRM requirement.

There is PadSync if you are on a mac: http://www.ecamm.com/mac/padsync/
