Regarding the video, the only issue I can see is that the rope jumps to a different position when you grab it, probably related to the indices mismatch above.
Also keep in mind that grabbing one particle will constrain the position of the rope at that point, but it will still be free to rotate around it. Ropes do not model torsion or orientation (unlike rods). You'll have to grab at least two particles if you wish to constrain its orientation. Then, there will be only one DOF left, along the rope's main axis.
