Video Player with the least battery drain?

view full story

http://forum.xda-developers.com – I use MXPlayer with the HW+ codec selected, and it works quite well, with low battery drain and full GPU acceleration. However, I've run into a little dilemma- the developer has a software version check that won't let me use it on 4.4.1. Any replacement suggestions for the time being? Thanks. ^^ (Also, .mkv playback capability is mandatory- the only video files I watch are in mkv :P ) (HowTos)
