Authoring DVDS

Which program is fastest at authoring and converting files and burning it onto DVDS?

no such thing.
Free dvdflick
or get Nero

1:30:00 divx encode to dvd (2pass) 5hours (more or less)

Then you have a slow-ass computer or crappy encoder. Even my fairly humble Athlon 64 can do a two-pass encode in TMPGEnc in under three hours for a 90 minute movie.

trial and error motherfucker, do you use it?
