I would like to be able to get at the original MPEG-2 without running the VOBs through DVD2AVI and re-encoding them (which takes forever). Is there a program that does this?

Ehm, well.. The VOBs are the original MPEG-2, just various "crap" around them. Depends really on what you want to do with the MPEG-2 file..

Basically, I want to strip away the "crap" and be left with a dvd-compliant MPEG-2 file at the original bitrate that I can just drop into an authoring program. I want to be able to do this because in some cases I'd rather just recreate (functionally, not graphically) the menu, rather than fiddle around with IFOedit, stripping VOB IDs, getting VTS sectors, etc., etc... (Frankly, I understand the process of authoring from scratch a helluva lot better.) In that case, while I might have to re-encode the main movie, I'd like to take the smaller "extras" VOBs and just use them directly.

Also, it occured to me that if you have a huge movie that you want to split across 2 discs, instead of doing it the way the Doom9 guide suggests--which, if I understand it correctly, involved figuring out which VOBs contain which chapters, then placing complete copies of those VOBs on each disc, then tweaking the IFO files to only point to certain chapters--it would be easier (from where I stand, it would be easier) to be able to extract the original set of MPEGs, which you could use TMPG to join and cut into just two master MPEGs to drop into your authoring program.

WP2K, I've done extactly what you are describing (with the menus) by extracting the movie with Smartripper.
I would select the move and then go to streams and demux the movie into m2v and its ac3 files. I then take this into Spruce.
I screen capture the menus using WinDVD and import the shots into spruce.
By leaving it as m2v and ac3, not changing it to Mpg2, saves me a LOT of time.
