Error parsing command-line options when using -c

Hello,
I am trying to create a DVD without menu from a single mpg file that I
have created using mplex -f8. The command is:

dvdauthor -t test.mpg -c 0,300,600,900,1200,1500... -o testdvd -t test.mpg

It seems that I have to enter the -t option and the filename twice. If I
leave out the first one, dvdauthor says:

ERR:  Must first specify -t, -m, or -x.


If I leave out the second one, another error message appears:

ERR:  Chapters defined without a file source.


My current version is 0.6.14. I do not know, if older versions are also
affected by that. Am I doing something wrong?
