iOS devices can't play many media types out of the box. At one time, you
had to learn to accept that or get used to transcoding your media files
- a time-consuming and tedious process at the best of times. That was
until apps like AVPlayerHD came around.
This iPad video player
app (iPhone version also available) lets you dump all kinds of video
files onto your tablet for immediate playback. Yes, it includes top
formats like MKV and Xvid, and yes you can transfer them through iTunes.
Videos have to be transferred as AVPlayerHD documents, but you can wave
goodbye to transcoding.
