If the "Nova - Submarines.mpg" argument (it will indeed be a single argument
from
the command line) goes through a bash script that references the argument
without
quoting it, bash will expand it.  CinemaSix has two examples of what _not_
to do.

CinemaSix.cmd:
#!/bin/sh

echo "----------------------------------------------------------"
echo "If you're running from the command line, use CinemaSix.cmd"
echo "----------------------------------------------------------"
export LD_LIBRARY_PATH=.
./CinemaSix.app $1 $2 $3 $4 $5

That last line should be:
./CinemaSix.app "$1" "$2" "$3" "$4" "$5"


CinemaSix.roku:
#!/bin/sh

echo "----------------------------------------------------------"
echo "If you're running from the command line, use CinemaSix.app"
echo "----------------------------------------------------------"
SXPATH=`echo "$0" | sed 's/\/CinemaSix.roku$//'`
cd $SXPATH
export LD_LIBRARY_PATH=$SXPATH
./CinemaSix.app

Both references to $SXPATH should be enclosed in quotes.  This will
otherwise fail
if the path to CinemaSix.roku contains spaces.
