VLC is the Swiss Army knife (nope, not you Perian) of media players and it has never baulked at any of the increasingly weird and wonderful formats we've thrown at it -- which is good because now it's available on Android. The unsupported, unofficial beta by user adridu59 is tailored to run on selected Gingerbread and Ice Cream Sandwich handsets. It's available to grab from the source link, with the caveat that as an unofficial build, it'll require a little bit of tinkering at your end
