Problems with MPEG Still Creation

[Rebooter]

When converting jpegs with the MPEG stills creator in VCDEasy, I get
the following error at random on some files:

"Need to start a new file but there is no %d in filename pattern"

The odd thing about it is that if I retry the files that give this error a few times it will usually do the conversion finally, so I don't think there's anything wrong with the jpegs themselves.

This problem appears to be fixed in 1.1.3.
