Video MMS won't play audio works fine

[spectre51]

I have a Lumia 900 with the latest updates and today received an mms message from my wife who has a iPhone 4S. She recorded a short video of our daughter playing. When I try to play the message I can hear the audio from the clip but the video doesn't play. Just stays on some blurring picture from the video. the file is a .3gp file. From what I have checked 3gp is supported just not sure why it isn't playing.

Anyone else have issues with video mms from iPhones?
