DVD chapters in wrong order - reordering chapters?

[boxit]

I've found that when converting various avi's (divx/xvid) using D2S at the end I've ended up with the movie in the wrong order.

I believe this is a known bug with D2S where it messes it up right at the end - during the 2nd part of the bit where it feeds it through Sonic Scenarist. I've had a look at the output at different stages, the one big vob in the DVD-mux folder is fine and in the right order, whereas the end one puts chapter 2 somewhere in the middle, chapter 3 and 4 at the end and chapter 5 follows chapter 1.

I've had a look at the IFO file in IFO edit and I think I can see where the error seems to lie. The thing is there seems to be a long way round of fixing it involving copying down the required values then completely rewriting the VTS_PGC_1 section manually.

Is there an easier way of doing this? Another program maybe? Or is this the only way? Also, would changing these values mess things up big style?

It may be quicker to re-encode the movie and hope that it all works properly this time, but I've already tried that three times.

I would like to point out that this is the first time I've played with IfoEdit or indeed IFO files in general.

I tried the thing I was going to try and it seems to work ok. It ain't an ideal way as it takes a while, but for those also with the same problem looking for a solution here be a step by step thing.

1) Open VTS_01_0.IFO in IfoEdit
2) In the bottom pane take note of what order the chapters are in (i.e. look at the V/C ID)
3) In the top pane, click on "VTS_PGCITI", expand this branch, then click on the branch that has been expanded (VTS_PGC_1).
4) Click on the "Copy to Clipboard" at the bottom of the screen and paste into excel or similar (this step is to save manually having to take note of the values).
5) Scroll down to the "Cell Playback" section - this is where most of the values you have to change are.
6) Going down the list, starting at cell 2 (assuming that's where your chapters started going wrong) rewrite all the values to what they should be - I find that "Cell Type (Angle)" should always be changed to 8, with "entry point sector", "start sector of last VOBU" and "last sector of this cell" also being changed to the values you've taken note of. You should also check the playback time value. (this is the time consuming bit, you may find it helps if you reorder them in excel first, using cut and paste, also having the panes side-by-side could help)
7) Once you've got down to and changed the last "cell", keep on going to the next section "Cell positioon in VOB". Go down this list changing the values also. It's a bit easier this time as it should read "1, 1, 1, 2, 1, 3, 1, 4, 1, 5, 1, 6, etc." as you go down the list.
8) Save and close.
9) Test using your favourite software DVD player.
10) Burn if successful.

If anyone has a quicker way of doing this I'd like to hear it as I've got another few movies that need reordering and this is a tad time consuming.
