This is why, as has been explained in my previous article on MKV handling and playback, you either convert the container to the already iOS-compatible MP4 / M4V / MOV (these are interchangeable from now, I refer to them as “ m4v” for simplicity) or jailbreak and use players (currently, XBMC or RushPlayer+ (quick review of the latter HERE)) that, not being constrained by Apple's very strict (and, in this case (too), absolutely unnecessary) restrictions, can utilize the hardware decoder to correctly decode the video.

Software-only decoding in third-party video players is useless over 720p resolutions (for example, at 1080p), no matter what some people say. Unfortunately, as has already pointed out in several of my articles, it can't be played back on iDevices natively that is, with hardware-assisted decoding. MKV, because of its being both open and very flexible, is a highly popular video container format today this is why iOS forums are full of discussions of using, playing it (see for example THIS, new thread).
