Yes it can play Mp4
You can by downloading an app on your PC/laptop then plugging your mp4 into it and downloading on your mp4. (it wont work if you have an mp3 it must be mp4)

MP4.
iTunes downloaded video movies TV shows files are in .M4V formats but not MP4, you can not get a MP4 file unless you convert M4V to MP4. I suggest to get an software to help you and read the relative links.
In my opinion i believe mp4 is better. is takes u less hard disk space and also has very good quality. go with mp4 if you want all that.
go to itunes
All you need to do is either go to the settings on the mp4 player(if there is a screen) and hit reset. Or you could plug it into the computer with a USB cord and right click on the name of the mp4 player when the computer accepts it as a device and then you click on format.
