Premiere Elements 9.0/9.0.1 was notorious due to many of its menu not retaining the background replacements in the finished DVD-VIDEO disc playback. The fix that we found was to add audio muted or non muted to the menu in the Disk Menus section of the program. It appears that these problems were gone in Premiere Elements 10, and I did report that at the time. From time to time, you find a menu whose buttons do not respond to the TV remote. But other than that, not much going on that is not typically explained away by overlapping objects, text maneuvers, spacing of menu markers, and related matters.
Since the project preset direct the program as to what set of the menu .psd set (s, w, or hd) will be available to you in Disc Menus, let us start with:
a. What are you setting as your Premiere Elements 10 Mac project preset? What is the size of this project as reflected in the burn to Quality Area for Space Required and Bitrate?
b. In the upper right corner of the Movie Reel menu choice is there a "HD" label or none?
c. Are you replacing background in both main and scene menus? How many scene markers, how many main menu markers, and how many stop markers and how placed?
d. When you preview the menu, are you getting any messages about object overlapping?
Let us start here and then decide what next.
Welcome to the forum.
While ATR works with you on the Menu, you might want to pick up a 5-pack of DVD-RW discs, to allow you to test your Projects, without burning "coasters." I do not recommend delivering on a DVD-RW, but they are great for testing, and for all major Projects, I will always use one, to verify that all is working fine. All of my computer multi-drives, and all of my test DVD/BD players can handle DVD-RW.
Quick question. Did you mean to say that you were using the disc menu theme News Reel rather than Movie Reel?
I have one of those try this, although I believe in systematic troubleshooting.
I went to take a first hand look at News Reel disc menu in Premiere Elements 10. I set for NTSC DV Standard since I did not know the project preset you are using for your project to which you want to apply this menu.
As it turned out, I could apply any of the menus in that group, except News Real. What worked for me to be able to use this theme was to delete the Adobe Premiere Elements Prefs file. Then it looked great in Disc Menus section of the program as well as at play back time of the DVD-VIDEO standard on DVD which used it as a menu. Although it is not a fit for your issue, maybe give it a try.
Local Disk C
and in the 10.0 Folder is the Adobe Premiere Elements Prefs file that you delete.
Make sure that your are working with Folder Options Show Hidden Files, Folders, and Drives On.
