Need advice on encoding/authoring

[psibay]

I have downloaded an X-MEN series from Season1 to Season5, this are all AVI format. I collected this info from GSpot software most of the files are different from each other. Here are the rough results.

[Codecs]
DIV3
DIV3/DIV4

[x:y]

352x240
432x324
320x240

[FPS]
29.9
25
14.9
30

My aim is to make this into DVD with chapters and menus, 2 DVD's since this are all 6.65G's

My questions:

1. Best encoding software/format for this type?
2. Good authoring softwares you can advice?
3. Should i stick to a standard FPS/screen size? what's best for a typical TV.
Any advice would be nice just to guide me in the right and better path.
Thanks in advance!

Buy what's available on DVD. Wait for the rest.
Read the rules - Downloaded TV shows = warez.
