type it in with no parameters and it will give you lots of help.

composite: ivtvctl -l 1
s-video: ivtvctl -l 2
coax? same as composite: ivtvctl -l 1

This module controls the Philips SAA7115 video decoder driver and is
responsible for the video decoding.
not sure about a 250mce I think it's the same.

This module allows your ivtv device (PVR350) to act as a framebuffer (eg
for X or as a console)
You can then use the standard Xorg/XFree86 fbdev but *much* better
performance is obtained by
using the ivtvfbdev from FIXME.
