Is it possible to instantaneously prepare an MPEG-2 file for DVD?

Hi. Does anyone know whether it's possible to prepare an MPEG-2 file for DVD nearly instantaneously -- without having to wait for a long encoding process?

Given that DVD contains MPEG-2 files (with .vob extensions), one would think that no lengthy encoding process is necessary. However, I've yet to find a software program that quickly prepares generic MPEG-2 for DVD. (Sony DVD Architect does do it nearly instantaneously, but the MPEG-2 files have to be specifically encoded for that program.)

I tried doing it manually -- changing a file extension from .mpg to .vob, inserting the file into a VIDEO_TS folder, and burning it onto a DVD. While the video worked, there was no audio.

Is it even possible to prepare an MPEG-2 file for DVD, i.e. create the DVD structure manually, by simply changing the file names and creating a VIDEO_TS folder? Or is a software program necessary in order to do so? (As .vob files can be no larger than 1GB, I suppose it would be impossible to manually set up an MPEG-2 file that larger than 1GB.) If the latter, does anyone know of any software programs that will structure a generic MPEG-2 file for DVD nearly instantaneously?

What I do is transfer videotapes to DVD. I'd like to eliminate as much rendering and encoding as possible in order to make the process quicker and more efficient. Currently I capture the video to AVI format, so I need to convert those AVIs to MPEG-2 for DVD. I know of hardware that enables capturing directly to MPEG-2, but I haven't invested in it because I'm not sure that MPEG-2 can be prepared for DVD quickly and seamlessly.

I would think the technology for that exists, given that set-top DVD recorders record via MPEG-2 directly to DVD instantaneously with no re-rendering. If DVD recorders can do it, one would think someone on a computer could too.

Any insights?

Renaming to .vob is not enough -- here's a hint from manual on "mplex" (an open-source tool):

"Format 8: DVD (with NAV sectors). Don't get too excited.  This is really a very minimal mux format.  It includes empty versions of the peculiar VOBU start sectors DVD VOB's include.  This is enough to persuade some hardware players to play the stream but is a long way from full DVD authoring"
