Why do some (older) DVDs upscale so badly on a 4K TV; is their native resolution lower than new ones

Update: To clarify, I am asking why some, not all, DVDs look awful, whereas others look great.

Answers:

While all DVDs are at the same resolution (520p) not all DVD transfers are equal.

Some DVDs were mastered from film while others used video tape for their source material. This is going to create a big difference in the quality of the DVD image. While it might look ok at its native resolution, lower quality mastered images aren't going to upscale as well - especially going up to 4k.

Note: This only applies to actual DVDs which are at a much lower resolution than blu-ray, so you're going to see significant differences between upscaling DVD to 4k vs. upscaling blu-ray to 4k.

No, the upscaling process was wonky in the early days.

Are you really asking why a DVD player that predates 4K resolutions does not support upscaling to 4K?

Do you also complain that your record player scratches your CDs?

It's the DVD Player. You need to get one that has 4K upscaling.
