Looking at the description and the fact that you said that you can capture from a VCR, I would say YES to all the above as long as the DVD player/Playstation 2 have the same outputs as the VCR which most should. The Moviebox comes with Svideo and Composite input and output conections.
You basically do the same thing as you are doing now with the VCR except the image will come from your DVD player or Playstation 2.
Wish you well and WELCOME to the board. This is a great source of information.
