I think if you pipe stderr to /dev/null, it should stop the messages from the program.
Code:
program --start-now /home/jack/me.iso 2>/dev/null 1>/dev/null
Just as a side note, does anyone know why 2>&1 1>/dev/null is not the same as piping 1 and 2 to /dev/null like 1>/dev/null 2>/dev/null?
good luck,
