I really see no reason why anyone would run wine just to recode a video, unless it's some extremely esoteric codec (not the case) or it's out of laziness.
We have very good encoders which are command lines tools, yes. But we have also graphical frontends for all of them, and besides that, I can't see what's the problem with command lines tools, though I guess that's about tastes.
Just look around a bit and you will see dozens of them. For example, in the site of mplayer you can see frontends for mplayer and mencoder:
And that's just for mplayer. You have ffmpeg, xine and some others, which their respective frontends as well. I can't advise you to use one or another, just look around and google a bit. Converting videos to divx is not a mysterious operation, millions of persons do it, so it shouldn't be something difficult to do.
I can't advise you about frontends just because I use mencoder in command line. If you are not scared about the command line, you might find this useful for dvds:
There are lots of howtos and wikis around with examples, a random one:
