I searched but I couldn't find something that addressed this specific problem.
I already had successfully followed this guide (http://forum.doom9.org/showthread.php?t=84887) (with some variations, such as using ffmpeg instead of BeSweet and only using Ifoedit rather than Muxman or ReJig - all of which were mentioned therein anyway), with other DVDs in the past, and even for this project it worked for the main titles.
My current issue is that these DVDs also use PCM audio for their menus. Normally I wouldn't think anything of it, but in these cases compressing the audio could make the difference of needing a single-layer as opposed to dual-layer DVD, and I also just wanted to optimize time for later burning.
Since PgcDemux has the ability to demux menus I simply used it the way the guide I already linked to describes doing with the main PGCs. I reassembled the video, audio, and subpictures in Ifoedit and then attempted to use Vobblanker's Menu->Cells->Replace option to switch out the original 99 MB menu for the 12 MB one that I had created simply by compressing the audio. It didn't complain and processed without errors.
When I went to test it in VLC (and later, after writing an ISO image, mounting it and trying MPC), I found that the menu's navigation buttons no longer register at all - no highlighting, nothing. I'm guessing either it's something in Ifoedit (as I'm sure it thinks the video, audio, and subpictures aren't a menu but a main title), or that I'm trying to make Vobblanker do something it can't.
Is there a way possible to do this or is this just something I'll have to live with, either with non-working menus or menus with PCM audio?
NOTE: The menus on these discs are still - they use what appears to be a full-length song, however.
