Track-at-once recording on DVD-R

Can anyone direct me to a commercial authoring package that supports track-at-once recording on DVD-R media?

I want to create a DVD-R disc with a recorded track in an open session, and later add a second track and close the session/disc.

To my knowledge, TAO is not theoretically/technically possible when recording on DVD media, regardless whether they are “-” or “+”

TAO on DVD - not seen that in action so far.

You can use Multisession instead.
