with the +4 the amp is on without it the amp is off. If you want to test you can update your kernel and compile ( no clean or mrpropper is necissary) then modprobe -r ivtv then modprobe ivtv. you may have to do the same with tuner but I believe when I tested this on 11-11-2006 that was all I needed to do.
