I just had virtually this same issue. I was trying to transfer a 1080p .mp4 video from my Windows 7 computer to my iPhone 5 and every attempt resulted in the "ERROR "Write Failed":Asset may not be compatible with this device" message.
10 minutes prior to attempting the aforementioned transfer, I successfully transferred a 720p .mp4 video using the same method (computer > iPhone). So when the 1080p transfer failed, I compared the two files' codec and they were the same. I concluded that the problem may be that Photo Transfer App does not support the transfer of 1080p video files at all, or if it does, they must be in a .mov or .m4v format.
It seemed absurd to me that Photo Transfer App doesn't support the transfer of 1080p video files, so I found these community forums and searched for the "Write failed" error, and found your post. I read Enrique Rodriguez' last reply, which mentioned that this issue may be related to having spaces in the file name.
His suggestion seemed very plausible to me so I immediately renamed the video file on my computer from "The Script - Hall of Fame ft. will.i.am.mp4" to "The_Script_Hall_of_Fame_ft._will.i.am.mp4". (I replaced all spaces with underscores). I anxiously attempted the transfer again and IT WORKED PERFECTLY!
Here are all the steps I took to resolve the "ERROR "Write Failed":Asset may not be compatible with this device" error:
*NOTE:* I was using a Windows 7 computer to transfer a 1080p .mp4 video file to an iPhone 5, using the Web Browser transfer method.
Replace ALL spaces in the file name of the video you wish to transfer with underscores.*1
1 - You can probably replace the spaces with characters besides underscores. I used underscores because they most closely resemble spaces.
2 - It's most likely not necessary to force-quit all the running applications. I just like to be extremely thorough...I'm a software developer and do a LOT of debugging, so being thorough and documenting problems and solutions is second nature to me :)
