If you're in the clear because the video you want to watch is unprotected I can offer a couple of options for viewing it. NXP Software's $4 CineXPlayer HD can play a wide variety of video formats including those compatible with iTunes. But I might recommend instead Good.iWare's $5 GoodReader for iPad. Although the company touts it as a PDF reader, I keep a copy on my iOS devices because it can open most files I throw at it, including common audio and video files.
