What do you mean by "overlay"?

That's not correct.
DVD is almost always interlaced or telecined. Depending on who created them, some DVD's are purely progressive but encoded as interlaced. There are several variations.
Standard BlueRay can be interlaced or progressive. 1920x1080 can be progressive if the originals are at progressive film speed (23.97 or 24 fps). 1920x1080 is otherwise interlaced at 29.97 or 25 fps. The same holds true for 1440x1080 BluRay.
1280x720 standard BluRay is always progressive at 23.97, 24, 50, or 59.94 fps.
Standard-definiton BluRay is interlaced or telecined at 25 or 29.97 fps.
There are variations on these standards, meaning that some people make non-standard videos.

Can't answer that. No one knows anything about your source videos.
