Roxio Toast or Popcorn? differences?

Question

i will have to burn DIVX, mp4, acv1, DX50, XVID and h.264 (AVI, WMV, MOV, MP4 files). i want to make them as DVD-Video to play them on dvd player. i know Roxios Toast and Popcorn will do that. i dont know if the cheaper Popcorn could do the job or would be Toast better? i only want to include a background picture in the mainmenu and split the movie into chapters. of course the quality should be as the original without loss. i dont record any DV stuff, only highly compressed videofiles. (mostly one hour movie is only about up to 1GB big.)
what can Toast do what Popcorn wont? when is Toast the better solution instead of Popcorn?
little sidenote about why i cant use iDVD: i just burned another XVID with "Burn", a freeware dvd creation tool. and that works fine as well. iDVD really has its problems with XVIDs. i read that "if you can play it with QT, than you can import it into iDVD"...thats right BUT how about the final results? well, maybe theres an add-on that makes XVID 100% compatible with iDVD?

Answer 1

if i want to watch my AVIs/DivX/Xvid/MP4s on a dvd player, isnt it better to just burn them to a DivX-DVD instead of encoding them into a DVD-Video? because my DVD-Player is DivX certified and should be able to play them (never tried that before). and Toast (or whatever tool i will use) doesnt has to convert anything. it just burns them to a DVD and the dvd player can play it. of course i dont have chapters and menus then.
are h.264, Xvid, AVI, MP4, AVC all DivX compatible codecs? because the videos i am talking about have all these different codecs. btw: these videos are gaming sessions (from different games) that i dowloaded from the internet. thats why they are already compressed and i think it wont make sense to convert them onto a mpeg2 dvd format.
what do you think?
