MacOS – iMovie 10 Project Lost

I would start by checking out Software Update to make sure that there are not any current updated for iMovie '09. I would then just try to export the project in a resolution of your choice to the desktop (or wherever you prefer), and just use Disk Utility to burn it from there. This will make sure that you at least have a hard backup of the project, and this may be more effective as you're not trying to run two programs at once (as iMovie is transferring to iDVD). This is key as your system may not have enough RAM to do two high-end processes at once (I don't know your system, so this is only an assumption). This being said, I would try to make sure that you have the fewest amount of programs running during this time period I would then try to take the exported project from the desktop, and throw it into iDVD to burn it with the menus of your liking. I hope this helps, and let me know if you have any more questions.

Note: If you are on a laptop make sure it's plugged in, and that you are running a program like Caffeine to keep it from falling asleep during this process.

Open Finder, on the far left of your Dock, then click "Applications" on the sidebar, then double-click "Utilities", then "Terminal". In the window that shows up, paste this in:

term="$(osascript -e 'text returned of (display dialog "What do you want to find?" default answer "rcproject")')"; d=0; for x in $(find ~ -iregex ".*$term.*" | sed 's/ /\ /g'); do let d++; osascript -e 'on run argv' -e 'tell app "Finder" to reveal (POSIX file (item 1 of argv) as string)' -e end "$x" >/dev/null; if [[ d -gt 10 ]]; then echo "Press Control-C to quit."; fi done; if [[ $d -ne 0 ]]; then open -a Finder; else v="$(osascript -e 'button returned of (display dialog "No files were found. Try again looking everywhere?")')"; if [[ $v = OK ]]; then for x in $(find / -iregex ".*$term.*" 2>/dev/null | sed 's/ /\ /g'); do let d++; osascript -e 'on run argv' -e 'tell app "Finder" to reveal (POSIX file (item 1 of argv) as string)' -e end "$x" >/dev/null; done; open -a Finder; fi; fi; open ~/Movies/ #END

^{If you're having trouble selecting it all, double-click the first word ("term"), then scroll all the way to the right, then hold shift and click on where it says "END".}

Press return ↩ if another window doesn't show up.

Then, the window should ask what you want to find. Leave what's in there at first, because rcproject should match all iMovie files. If it says it couldn't find any files, click OK. If it still couldn't find any files (it might take a long time to look), then repeat the above with something else (like Klass 6B-9B). I doubt you will find anything else, unfortunately.

A Finder window will pop up with your Movies folder. If any others show up behind it, try dragging those things (only .rcprojects will work for this) into the iMovie Projects folder in that window.

I don't know where it says you have two projects, but if this doesn't work, it's possible that the file got corrupted somehow…
