It seems that they are available on yggtorrent.
Didn’t get it downloaded but I found another 720p in Portuguese.
To me it seems just to be a (although good) upscale of the DVD-Master.
I just went through the french “720p” set. They are 100% upscales.
Went through them side by side and frame by frame with a qtgmc rip I did of my own dvd’s.
The 720p is clearly just an upscale done with a little bit of sharpening filters and slightly brightened.
