You can't.
You could do it if you provided a specific player, which decoded the video file using information specific to the PC running the application (in much the same way the DRM does) but the file has to be specifically encrypted for the PC (or the player needs to be in contact with the video supplier at all times, as Steam does for it's games) and the file must not be playable using any other player.

And guess what: if your system becomes popular, it'll be cracked very, very quickly...
