Motorola E815 / E816 Hollywood

I have taken a few shot video's from my E815 . I used me trans-flash card to transfer them to my computer . How do I get my computer to play them ? the format the video's are in is .3g2

I have a windows based computer with Realplayer 10.5, Windows media player 9.0, and Quicktime player 6.5. None of these programs will play my video's ☹️

Thanks for any help ..
