Failed

My project has one title with two buttons and a single clip (just under 25 minutes). I'm not sure why it is having issues now, with the exact same settings it worked with the initial copy. Thanks for any help.

Do you have the log from this run (when it worked)?
For me this looks like a 'half' command line:
spumux -s 0 "C:\MIKETEMPOMG\dvd-tmp\menu1-0.mpg_spumux.xml"

The syntax should look like:
spumux -s 0 "C:\MIKETEMPOMG\dvd-tmp\menu1-0.mpg_spumux.xml" <
"C:\MIKETEMPOMG\dvd-tmp\menu1-0.mpg" >
"C:\MIKETEMPOMG\dvd-tmp\menu1-1.mpg"
