The capture card is a Blackmagic Decklink plus

What other solutions can you think of?

Do they sell DVD players with SDI Output?

Should I buy some type of scaler and switcher system so I can play multiple sources?

The question about playing a DVD has been asked a few times now.

And I would like to either say the only way it can be done is to transfer the movie to quicktime and upload it to a folder or no problem our system is setup to take DVD, Live Video, and a multitude of other external inputs.
