I don't intend to use video in container fields on the IPhone when shared with the desktop database. However just for a test only I did put a short video of 30 seconds in the container field in Filemaker Go using the IPhone. When I went to play it back in the desktop container field I rec'd a similar message that the file extension (.mov in this case) "does not match the file format" and could not play the video.
There is no problem at all when a photo is put in the container field via the IPhone. You can see it on the desktop fine.
I even tried downloading and installing the VLC Media Player mentioned in the Google link by davidlanders above and the same problem occurs.
What would likely solve the problem is if you could - choose - what audio format to record sound in, on the IPhone 4s.
