Hi Rodrigo!
Happily, I can say yes there is a way.  You can put the information that would have been entered in the initial MD Movie dialog into a small text file called "metafile" and then open the metafile with a command, e.g. something like: 

open md:/Users/meng/Desktop/mymetafile

There is some description of this below the formats table in the "MD Movie" input section:
... specifically

See also "MD Movie metafile" in the general input formats table:

I hope this helps,
