Interlace setting can't be changed

I'm using VMS11 to upscale DV recordings to HD and adding blurred pillars.

When rendering AVC BluRay disks, the Interlace selector is grayed out and frozen in either top field first or progressive for almost all the profiles. Now, as it turns out, when I burn a 60i disk with the profile being stuck in top field first, it seems to be actually handling the bottom field first source material properly. On playback there isn't any combing or shaking. Using MediaInfo on the m2ts file in the STREAM folder shows that the video is upper field first.

Curious what magic the Sony software is doing to reverse the interlace without causing any shaking or combing on playback. I've got de-interlace method set to interpolate.

I really don't understand upper field first vs lower field first distinction. The TV is just painting an upper if it's an upper, then painting a lower if it's a lower. How can their be a "first" or "second" when it's simply alternating between upper and lower?

If you shift picture 1 pixel up, even lines become odd and vice versa. Back in 8 version people did it manually, but as of now vegas can do it itself.

You don't need to understand field order. Sony gets it right and a DVD can be either upper or lower.

If you render an interlaced video in Movie Studio, you will get an interlaced DVD. It's that simple.
