I think you're trying to push it beyond what it's capable of doing, qumi. Sorry.
But it sounds like the basic functions are working just as they should, FWIW.
Thanks for replying Steve.
I've been battling with this on and off for a couple of days. Behaviour of my custom DVD template is not stable unfortunately, from project to project.
For example, I make a copy of the entire psd file (the one used in PE4 for the main menu template (Football_pal_s_mm.psd), rename my original to project it from being read or overwritten, then change some of the titles. I then apply this custom dvd template in a project and let say Title Line 1 through Title Line 5 are showing ok.
If I make another copy of this psd file, and change just the text on say Title Line 2 and Title Line 3, when I apply the template in another project, the new text is seen (the psd file layer is imported correctly into PE4) but now for unexplained reasons, Title Lines 4 and 5 no longer show in PE4 even though they are showing in the PSD file. I can't seem to find out why this behaviour occurs (i'm working blind here, no relevant documentation that I can track down on these functions).
I'm trying to figure out what determines the visibility of a layer in the PSD file of the template, versus what determines the visibility of the same layer after it has been read/imported into/by PE4.
It would appear to me that gumi's issues reflect the fall out of a learning process rather than "trying to push it beyond what it's capable of doing". It being Premiere Elements.
It has been my experience and, I am sure yours as well, that strict attention to details of Adobe DVD Menu Creation requirements (in .psd and in placement of .psd/folder/) determines what is going to show up or not show up in the DVD menu in the Disc Menu section of Premiere Elements. Even the misplacement of a punctuation mark can create the failure. A case in point...if a person is customizing an existing DVD main menu by Photoshop Elements editing the main menu .psd in the program files, and decides to gain extra buttons by copying existing ones, it becomes necessary to open the Layer Set copy and make sure the sub Layer Set is named (^^) and not (^). If you do not check and correct if necessary, you most probably will end up with text in the Disc Menu section that cannot be edited. In that copy process apparently the (^^) of the original is changing to (^).
I think the task is doable, but the current workflow needs some microscopic examination and refinement.
I agree with you, if I am reading the OP's problems correctly.
As you point out, the full, and exact conventions MUST be followed.
Because of the semi-automatic authoring functions in PrE, there are a few additional considerations, beyond what would be required in, say an Adobe Encore Menu. Also, as PrE uses Menu Sets, each of the two Menus (Main and Scene Selection) must follow those conventions exactly, or issues will result.
When creating Menu Sets for PrE, I find it very useful to have one of the included Menu Sets Open in Photoshop, just to check that everything is, as it must be, including the Layer names (all characters, and especially before any space) are critical.
Good luck to the OP,
