OK, gg will be adding a warning before the next builds and I will include it in the manual too.
A warning has been added and checked into GIT so will be available in the next builds. Hopefully, this will avoid future users being flummoxed by this problem. A warning box popups that is scrollable and will look similar to the following:
3 job EDLs begin position beyond end of media
1: /tmp/test.xml
2: /tmp/test.xml
3: /tmp/test.xml
press cancel to abandon batch render
(IgorB: even though this warning may not be necessary, it is helpful to me for sure). Phyllis/GG
