I have just recently purchased the Nikon d90 and have run into a problem. When trying to transfer movies taken with the d90, there have been some instances where the movies do not transfer to my computer. I am running MAC OSX the latest version and run into this problem on iphoto as well as with the nikon software that comes with the camera. An error message simply appears that says it can't transfer these files. Please help. I have searched some forums with other users experiencing the same issue but have found no solution.
