Alot less hassle!
The whole point of my original post was to show how to clean up the SVCD's into a single KVCD. I don't know about all of y'all but I'm a lazy bastard and don't like to get up halfway through a movie I especially don't like it when the movie gets cut halfway through a sentence or word. Using my method you can have a 100% seamless, perfect movie from beginning to end. You can dump the resulting MPG into VCDEasy to add chapters or do whatever afterwards -- this just gets you one file for the whole movie with guaranteed audio sync and no glitches.

EDIT: This method also makes it very easy to take, say, a three disc movie and encode it down to two -- just make the script for the whole movie all joined together, load that as a source and then split that, or do some math and merge the first disc with whatever half of the 2nd you want, then the other half of the 2nd with the rest of the 3rd.

Yes, you can just put two MPG's onto once disc, but you still have to eliminate the two second overlap in the middle. If you have to do that anyway, why not just add an extra period or two and some plus signs into your AVISynth script and merge the two together? I, personally, think it would be a LOT more tedious to encode two separate files finding two different CQ values than just mushing them together and finding one CQ value for the whole thing.

I've done lots of these and invested way too much time into it, and I've found that making a script and cranking out the audio in VirtualDub or similar is the best route that will guarantee no f*ckups in between with perfect cutting of the audio and resulting perfect sync with the movie. Yes, it can be tedious but the result is pristine. Once you've done enough of these, you can do the whole first few steps (ie: everything prior to file size prediction) in a matter of minutes, and when you've really done enough you'll start to notice patterns.

For example, using Jorel's method (I think it was his) for CQ prediction where you use triple the framerate, if you encode your audio at 128k, you'll find that your target file size will always be roughly 36 megs, which means using standard CQ prediction methods, your target size should be around 12. Et voila, no more KVCD Predictor to find target file sizes. Optimization is fun isn't it?

Again, this guide wasn't meant to be just a 'how to put two discs into one as quickly as possible' guide.. it's a 'how to put two overlapping discs into one high-quality seamless disc as efficiently as possible' guide. I know many programs automatically overlap the two discs, and A) I don't like bad splits and B) I don't like switching discs halfway through the movie (although I have to admit, the switch is usually perfect for a smoke break )

Fare thee well.

I just tried to run a mpeg file thru dvd2avi v1.77 and nothing happened. Is there something I left out?

Also when I tried to encode in cqmatic it said I needed a tmpg file. How do I make one when yr instructions it says encode in cqmatic?

If it's PAL, leave it alone.
Can you explain how to do this step? I have mpg1 format files not 2, and when I run it through dvd2avi as you suggest, nothing happens. Any suggestions?

Man, you are dealing with VCD files and you look into a "SVCD to KVCD" thread.
Make a search on the forum, there a a lot of "VCD to KVCD" or "MPEG1 to VCD" threads, with all the answer you need into them.
