Multiple 360 VR video player in Unity

I already know how to implement a 360 equirectangular VR video player in Unity3D as the code below shows (by following the steps here). Now in my case, I have the same equirectangular video tiled into two parts (left-half and right-half), and want to map both to the sphere (two players glued together) and play as if the user is watching a single video. Ideally there should be no sync issues (I tested this on 2D media player and it's perfect; you can not say the video is cut into two haves!). How can I do that in Unity3D?

I thought it is as simple as drag-n-drop whatever videos we have into the surface of sphere, but not sure if it is that simple.

using UnityEngine; using System.Collections;

 public class VideoViewer : MonoBehaviour
 {
     public GameObject leftSphere, rightSphere;

     void Start ()
     {
         ((MovieTexture)leftSphere.renderer.material.mainTexture).Play ();
         ((MovieTexture)rightSphere.renderer.material.mainTexture).Play ();
     }

 }
