The built in player does play MP4 files but only when the file is saved in camera roll in a valid way like copying using a cable, recorded video etc. Somehow when a file is transferred using Moliplayer's Wifi option, the system does not recognize it but the moliplayer does.
I have observed this behaviour with files when the files are renamed using the windows explorer in the MTP mode, they are not recognized by the system. I guess only files that are routed through the WP8's native apps are recognized. Hence only moliplayer recognizes the files transferred into Camera Roll using its Wifi option
