I am confused with Procoder 3. When I have a progressive source and want to author a progessive NTSCFILM DVD which option should I select under Target framerate?

I assume the 23.976p -> 29.97i (2-3 pulldown) is what I want but I notice when I select this I am getting odd interlace artifacts when playing the output VOBs on my monitor. Is this because VLC player is doing the pulldown on the PC or has the output file actually been interlaced?

thanks for help
