Hi there and be welcome!
The reason why this won't work is very easy: your drive cannot burn to dual layer media. This is a somewhat older burner, only supporting burning to single layer media.
With this drive, the only way to fit a DVD bigger than DVD5 on a DVDR is to either transcode the whole DVD, re-encode the whole DVD, leave parts off (doesn't work when the primary movie + primary audio track is over DVD5 size) or split into 2 discs. There's no other way with this drive, I'm sorry!
