Cursor selection does not follow chapter order on sub-menu

Question

I used iMovieHD6 to add chapter markers to my large DVD project. They "shared" very nicely into iDVD8 and the Chapter Selection sub-menus were created nicely.
The problem is that when I use the cursor arrows on the DVD remote (real or virtual, in or out of iDVD), the highlight jumps around the sub-menu items rather than moving in a logical order. For example, I have 4 sub-menus with 6 chapters in each. Let's use numbers for them starting with the upper left they are 1,2,3 and then at the lower left they begin 4,5,6. I am using the Reflection White theme. When I press the right remote cursor button it will move from 1 to 2 to 5 to 6 to 3 to 4 and back to 1. Note that this order is not the same for each sub-menu, but none of them go 1,2,3,4,5,6.
I don't know what might be wrong or how to correct it, but I have a really big project that is otherwise perfect and I'd really like to get it out, please help!
Thanks.

Answer 1

I just wanted to add this before closing this topic.
After poking around with the Reflection theme I better understood what Len was talking about. It appears that there are no modifiable parameters in the theme itself that control the order of cursor's motion through the buttons. That I assume is hard-coded into iDVD and follows a pre-programmed logic.
The point of failure is the position and orientation of the buttons in the Reflection theme's sub-menus when added automatically. They are made to look to the viewer as though they are set on an angled surface and viewed at an angle from above. While our brains can process this effect nicely, iDVD's cursor logic doesn't fare as well.
The work-around is fairly simple: Realizing that iDVD treats all chapter buttons as though they are two-dimensional objects on a flat surface, you must re-arrange them so that from top-left to bottom-right they follow a logical order, with the first buttons higher and farther left than the later-selected buttons. You don't have to move them very far to get the desired result and it doesn't have to affect the overall appearance of the menu in a noticeable way.
A slight rearrangement in my case left the overall look of the chapter menu the same but yielded a zig-zag flow through the buttons as follows:
[1] [3] [5]
[2] [4] [6]
Pressing the right cursor key jumps from top left to bottom left to top center then bottom center then top right and finally bottom right before going back to the start. Granted this is not quite "right" in that if iDVD could "see" the menu the way my brain does it would go left to right across the upper row of buttons rather than zig-zagging, but I figure that as long as the user can understand how to get to the button they want it'll be fine.
If you really need your menu selection to move linearly left to right with those arrows and with the up/down arrow used to move it vertically, then you have to arrange the buttons on the menu in a rectangular pattern with the top of each row of buttons all in a nice horizontal line. Note that's not the same as the alignment line that Reflection provides for you, it's a true horizontal line in relation to the monitor screen.
I'd much prefer that iDVD revisit the logic of the cursor control code, perhaps adding the choice of allowing the numerical sequence of the chapters to dictate the order of the cursor's motion rather than their relative position on the screen, but since they don't call me for advice, the above will likely have to do.
