How does Hollywood do it??? (interlace question)

[tarrickb]

Just wondering, why don't DVD's and such have interlace lines when viewed on the computer with software that DOES NOT de-interlace (should see the interlace lines, such as VLC or CyberLink with the option to de-interlace deactivated).
There are a few DVDs where the intro appears interlaced, but the actual movie does not.


Let me know what you think...THANKS!

Broadcast (TV) source is transmitted interlaced. Film source is non-interlaced.

So a progressive source file doesn't need de-interlacing to look right
