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!
