The PS3 is a versatile and powerful system, capable of playing high-definition video games and Blu-ray disks at resolutions up to 1,080p. The PS3 is also compatible with many movie and audio formats, like MP3s, WMVs, MP4s and M4Vs. You can easily transfer and play an M4V on your PS3 if you have a storage device available. Of course, if you have M4V files that are protected by Digital Rights Management, they won't play on the PS3 since the point of DRM protection is to keep files from being copied and replayed indefinitely.
Transferring the Files

Click the "Start" button and select "Computer."
Double-click the USB flash drive to open it.
Locate the M4V file or files you want to watch on your PS3.
Drag and drop the M4V file or files into the drive window. You can select multiple files to drag in at once by holding the "Control" key while you click on them.
Remove the flash drive after the transfer is complete.
