Outputing to a DVD

Is there an way to output to a DVD from the ATEM Television Studio?

You need a DVD-Recorder for live recording TVS' output. It depends on Recorders input, whether it is possible to connect the TVS directly. When not, a converter is needed.

If you want to create the DVD later, you can record to a file (on connectes PC / MAC) and author the DVD using this file.

As Thomas said, a DVD recorder is needed.
You may want to check the JVC SR-HD2500 model, which is equipped with SDI input and has easy workflow : START-> STOP-> Finalize DVD.

One note though: only stereo audio supported!
(SDI embedded audio pair is selectable, but only by one pair!)
