Once again...BluRay encoded content must be put on *BluRay discs*... BluRay encoded content *cannot* be put on DVD discs. And vice versa - DVD encoded content must be put on DVD discs, it cannot be put on BluRay discs. They are read by completely different types of laser technology - BluRay discs have that name for a reason - they are literally read by Blue laser rays - DVDs are read by red lasers. DVD players cannot play BluRay discs. BluRay players that do not have the backward compatible DVD reading technology cannot play DVD discs (though most do).
DVD and BluRay are distinct formats, with their own unique and different encoding, and DVD discs and BluRay discs are not the same thing. If you want to make a DVD, you have to record DVD encoding on a DVD disc. If you want to make a BluRay, you have to record BluRay encoding on a BluRay disc. BluRay can only be encoded onto a BluRay disc - it cannot be done on a DVD disc. The discs are not even read by the same type of lasers. A DVD disc would not even have the storage capacity to handle the BluRay encoded content even if it could be put on there.
(please read this...and you can also look up countless other sources showing this, go to any general merchandise store and see that BluRay discs and DVD discs, BluRay and DVD burners are distinct, separate products and are not the same thing - you don't have to take my word for it - look it up)Differences between BluRay discs and DVD discs
“DVD encoded content must be put on DVD discs, it cannot be put on BluRay discs.”
Yes it can.
DVD movies use DVD-Video format which is the MPEG-2 codec.
BluRay supports this same codec which allows copying DVD movies to BluRay disks:

Video Codecs:
MPEG-2: Enhanced for HD, also used for playback of DVDs and HDTV recordings.
Saying a file can’t be played on a different storage format is just wrong. It’s like saying playing a mpeg video on a USB stick wouldn’t work if you put it on an HD or ssd or disc. The data is data.
