If you are outputting as DVD-Video, then it has to be interlaced according to DVD-Video specifications, unless you are doing VCD resolutions. That might be why it is automatically changing it to interlace.

You don't have to output DVD video as being Interlaced, you can choose Progressive if you want to, if you want to completely avoid interlacing errors during playback.
The modern DVD and Blu-ray players of today don't care, they play Progressive scanned DVDs with out problems.
Have done this with several DVDs, because the source material had very bad interlacing errors.

I've been producing progressive PAL DVDs since quite some time now, and nobody complained so far :)
The mean reason was to save quality on very long theater play recordings (gains was twofold: first during shoot where 25p give 6dB headroom over 50i -important for low-light plays- and second, during encoding as progressive is more efficient compression-wise than interlaced.
I have encoded up to 2h45m on a 4.7 GB DVD (as low as 3.5 Mbps VBR very good quality !)
