I converted a Vegas 12 veg file from 4X3 to 16X9, leaving everything else as is. I now want to utilize it in DVD Architect 6. However, I already authored a 4x3 DVD of this program (in DVD Architect 5x?). What is the best (and quickest?) methodology to get this 16x9 footage into the dar file I already have so that I do not have to start the authoring process over again? I already simply tried just adding the newly-rendered 16x9 mpg file to the existing dar file, but I was unable to remove the original 4x3 mpg file in the DVD Architect project. I gave the 16x9 veg file a new name prior to rendering to mpg and ac3 (separately), too, so this is not a source of conflict. Am I able to accomplish this simply, or must I go back to square 1 and completely re-author? Thanks in advance.
