this is my first post, so be gentle

i have searched the forum but i haven't found any posts that can answer me properly.

i'm authoring a dvd. my source material is on DV format. i edit it in premiere pro, save the project and open it in after effects to do some color correction, etc. then what i want to do is to render it to some lossless format so i can encode it to mpeg2 later.
then all sort of questions arise in me, mostly concerning colorspaces.

what lossless codec should i use??? i know that:
-dv uses 4:1:1 YUV
-both premiere and afterfx works in RGB24/32 so i assume that there is some kind of colorspace conversion
is this correct or there is a better solution?

is it right to use huffyuv? i saw that fddshow has a huffyuv version that works in other colorspaces than RGB, so...

can i use another lossless codec that yields better compression (alparysoft/MSU/Lagarith/FFV1)?

please excuse my n00bness... thanks
