Why do DVDs use Interlace?

[Echo147]

As the topic says.

Considering how great movies look as progressive, especially when ripped, why is interlaced content used at all on pressed DVDs?

It seems to be on anything other than a movie, TV shows for example.

Now all region DVD players are capable of playing and converting progressive material for an interlaced TV, so why isn't the source disc always progressive?

Kinda frustrates me when ripping TV show DVDs, having to use a deinterlace filter, and subsequently losing half the vertical resolution. Not just that but fast scrolling text can look awful after deinterlacing.

Perhaps because it was stored in an interlaced format when it was first recorded, before it was converted to a DVD.
