saa7134, aumix "video" input line command?

My saa7134 gives the following mixer settings:

[root@gorgon bttv-0.7.94]# aumix -d /dev/mixer3 -q
line1 50, 50, P
line2 50, 50, P
video 100, 100, R

but I don't see any way to tell aumix to
set the video input to 100 and record at
boot on the command line (line 1 would be:

  aumix -1R -199

but there's no flag for video input.
I can probably do this with saving the
settings to a file, but would rather not
if possible.
