Danny is correct, this is a bug with CS5 that Adobe has refused to release the fix for. They have it, and have distributed it to some of their beta testers, but will not release it to the public.
Another way to fix it is to modify the Blu-ray navigation commands using BDEdit after you have exported your Blu-ray project as a folder from Encore. I would like to thank Larry Applegate for providing this fix.
Open the BDMV folder in BDEdit, and do the following:
1) First, locate all your Movie Objects for each of your videos on the disc. You can browse your streams folder and find the stream of your main videos, then locate the Playlist in BDEdit that plays those streams. Then you can locate the Movie Objects that reference those Playlists. It sounds complicated, but once you find the first one, you will easily find the others. Each Movie Object that plays one of your main movies has 19 navigation commands or so. The others will have far fewer.
2) Make the following modifications to each of the Movie Objects that play your main videos:
Change Line 3 from “GoTo Line 6” to “Goto Line 8”
Change Line 7 from “Move GPR10, 0” to “Move GPR10, 62”
Delete Line 6 “Move GPR9, 0”
Once you have made those modifications to a Movie Object, you must hit save (lower left of BDEdit) before proceeding to the next Movie Object.
If you have a Pop-up menu that changes the subtitles… you will not be able to correct the issue as the pop-up menus are muxed into the videos and cannot be remuxed with this software. To avoid this, you can just have a pop-up menu that links to a regular menu where the subtitles are changed. Another option is to call Adobe and demand they provide you the fixed Encore executable… but I don’t think you will have much luck with that one.
I am working on a tutorial that should be ready by early next week.
Once your modifications are made, you can create an image using ImgBurn.
P.S. – These are PC programs. Larry Applegate has software for the Mac that can make these modifications as well.
