Default Rendering and interlacing-lines

SO, as i wrote in my other thread ("interlacing and resolution issues!") lines keep eliminating my attempts to create a watchable DVD of the movie i made. At first it seemed the problem originated in the small fact that i watched the clip on my computerscreen (aka "progressive"-screen) but now i have realized that the lines are still there even on television (whatever happened to televisions viewing material with dots instead of lines?). I use Field order: None (progressive) and Deinterlace method: None in project video properties and Field order: None (Progressive) in the render settings. the problem appear in both AVI and MPEG 2-format.

This site describes the problem in the faq section and redirects to another quite extensive site. The problem though is that the guy thats made the site has made everything extremely confusing not to mention completely unrelated to the functions of Sony vegas. An expert could probably process this information efficiently but i just feel completely lost while scrolling trough the site.

Now, if i have used a PAL miniDV camera to record the material:

1. Is the material recorded progressively or interlaced?

2. If the material is shot in 50 fps, what should i render it to since 50 fps isnīt a selectable frame rate in render settings?

3. If itīs progressive what settings do i choose in Sony vegas?

4. If itīs interlaced what settings do i choose in Sony Vegas?

5. Is there a way of fixing it without sacrificing quality?

The final question is based on the fact that i found it possible to render down to 24 fps which made the lines go away but the quality worse. How is this possible? What makes the lines turn from being lines that moves in a hypnotic fashion on the tv even while paused, to become clear though blurry white fields?
I donīt want to (and donīt think i should have to) sacrifice the quality in the version with the lines but i have to get rid of the lines in order for the film to be watchable.

Could it have to do with the format? I chose mpeg 2 and DVD architect PAL video stream and then in custom i chose DVD as output type. Other output-choices in render settings are SVCD, HDV, ATSC, D-VHS and MPEG 2.

Or could it perhaps have to do with downsizing ? Thereīs alot of talk about the need for resizing to solve these kinds of issues but no real reasons why resizing solves interlacing-issues and no directions as to how this resizing should take place.

As mentioned in the previous post the problem sticks around regardless of which deinterlace method i use (Blend, Interpolate and None-progressive) so it seems to have to do with something else.

I would REALLY appreciate help with this. Iīve been trying to fix it for a couple of weeks now and iīm starting to completely freak out (as you perhaps already have noticed). And even if you personally donīt know what i should do then perhaps you could redirect me to some Sony vegas-Interlacing-dvd-guru somewhere that can help me instead!? I would be VERY grateful!
