Nobody knows (except Corel) what those error codes mean, but "Encoding Menu Images", probably means that it's having trouble with one or more of your still images. If you're using JPEGs, you might try converting the images to bitmaps (BMP).
You can also try eliminating the stills, and add them back one at a time to find the problem file(s).
Whenever you have a "major problem" like this, it usually has [i]something[i] to do with one of your source audio/video/still files.
Head over heels,
No time to think.
It's like the whole world's
Out of... sync.
