"nfortunately for many video lovers, iOS devices have a limited number of codecs built in to the device, leaving users only able to play H.264 video, MP4, MOV, and MPEG-4. Even though the versatile VLC Player is no longer on the iPad, you still have some options. We recommend CineXPlayer, a $3.99 iPad app that lets you play Xvid and AVI file formats, complete with subtitle support."
