Is anyone able to play MKV on their phones? I've tried a couple videos and the screen is almost completely grayed out. Those videos were at 720p. I'm wondering if there's anyway around this (I kind of bought the droid x for MKV playback). I've seen the Galaxy S play 1080p MKV. Is it's GPU that much more powerful? Edit: I've also tried a 480 mkv file. And I used both Rockplayer and YX Flash but no dice.
