3g2 codecs

Hi I just got a samsung cell phone with video and picture. When I try to upload the video's to my computer it is in 3g2 format and my computor cannot play it. I've tried downloading all sorts of 3g2 and Mp4 codecs but nothing seems to work.
Has anyone had this problem and if so can you tell me how I can view my video's?
Thank you.

Download VLC media player, it'll be able to play it. If for some reason it can't, just search for a 3g2 to avi or mpeg converter.

Thanks I'll give that a shot.

I downloaded it and the video part worked but the sound didn't.

Then download a converter.

Oh.. I thought that was the converter.. I'm not the best techy. Thank you
