I quite often get videos of varying formats given to me by friends. These tend to be created on windows PCs and put on memory sticks. I have just joined the Apple set and bought a new iPad. I would like to view these videos on the ipad. Can I just ace the video files on an wi drive, air stash or similar device and view them using an app such as Cinexplayer? Is it that simple? Has anyone got experience of these devices?
