Audio no longer syncing/working on export in Motion 5

I am all of sudden encountering a huge problem with my Motion project towards the tail end of all my work. My project is 12 minutes long and consists mainly of still images and some short video clips. Also has several music clips. I have gotten all of the audio (music) perfectly timed with my project. It plays perfectly during playback in Motion, and I even sent to Compressor a few days ago and burned a DVD in DVDSP, and the audio was perfectly synced. All of a sudden today, that is no longer the case. When I exported to Compressor (using the same settings I always use (AC3 dolby digital for the audio and m2v for the video) and pulled it into DVDSP, all of the audio is now totally out of whack. And it's not just that it's a few seconds off or something easy like that. It is actually playing music and audio from my video clips that I trimmed out in Motion, or even that I keyframed the audio levels to mute (-96). Again, the project worked perfectly the other day, and I've done projects like this before that worked perfectly. I didn't do anything since my last DVD burn to this file other than the usual edits to my still images. In fact, I haven't even touched the audio. I am really freaking out because the project needs to be delivered to the client on Sunday! I tried restarting my computer, but that didn't do anything. I did a quick "share" of a short portion to Quicktime, and it's still all messed up. Can anyone help or wave a magic wand????
