quenc/avisynth questions?

[tacitus]

I am playing around with converting Over-the-Air High Def 1920x1080i content (already converted to MPEG 2) to a NTSC animorphic DVD using quenc. I do not understand how the settings in quenc interact with avisynth.
For example - if i use the following avisynth script:

mpeg2source("file")
bob()
BilinearResize(720,480)

Do I need to then re-interlace the video in the avisynth script Or does using the "MPEG-only settings" under Advanced Options - and checking "Interlaced Encoding" actually interlace it for me? Will using my own "MPEG-2 Only" interlace settings in avisynth script override the advanced options setting? Or visa-versa?

Thanks

Is high-def still 29.97fps?

mpeg2source("file") 
SeparateFields()
BilinearResize(720,240)# Each field is half the frame height
Interleave(SelectEven,SelectOdd)# Or Interleave(SelectOdd,SelectEven)
Weave()

AviSynth[/url] Documentation]Bob takes a clip and bob-deinterlaces it. This means that it enlarges each field into its own frame by interpolating between the lines. The top fields are nudged up a little bit compared with the bottom fields, so the picture will not actually appear to bob up and down. However, it will appear to "shimmer" in stationary scenes because the interpolation doesn't really reconstruct the other field very accurately.

Thanks - for the info - there does seem to be many ways of doing the same thing.

My High-def source is 29.97 fps.
