The client is providing the DVD and has created its content

They want to know if the catalyst can take a DVD from an external or the internal DVD player and use the movie recorded on the DVD as a layer in the Catalyst.

I know we could potentialy just take the movie off the DVD and upload it into a library folder, but that isn't what they are asking.

They want to see if the catalyst can use an external source like a DVD player to supply a layer of content to a presentation using the catalyst and DL-1

Currently our Catalyst only has a SDI Capture card

and the only DVD players I have are Firewire or Composite out

I have tried to use the Firewire input to play the DVD through an external DVD player but catalyst only recognized the Blackmagic Decklink capture card as the video input and would not let me use the firewire
