Well, the format HD-DVD is dead and gone. It lost the war with Bluray.
They never updated DVDSP in that regard. Ignore it.
Frankly, long-term, they’ll be no discs for playback. It’s all streaming, online, digital file. You could just make digital masters. Back em up to a couple of hard drives.
Alternatively, you can make Bluray (HD) masters from your HD edits. You’ll need a Bluray burner. Then make DVD (SD) from your SD and smaller stuff.
But, yes, FCP works well with Prores. Apple created it.
