No.  Before you do a 'make install' you'll have to backup your kernel
modules.  So I'd just back up all of
	
	/lib/modules/`uname -r`

The latest v4l-dvb only compiles on kernels from a certain version
forward.  The kernel FC-4 uses may be so old, that things won't compile.

And yes the install will replace you tuner drivers, core v4l modules,
dvb modules, etc.

The HVR-1600 requires at least these modules:

cx18      cx2341x   v4l2_common  videodev      i2c_algo_bit  i2c_core
dvb_core  mxl5005s  s5h1409      tuner_simple  tuner_types   tuner
tveeprom  cs5345

and maybe one of the tdaxxx modules.

ivtv needs a subset of the above, plus others.

For a working cx18 driver and HVR-1600, I'm almost certain that you'll
need a newer kernel than the one that came with FC-4 when it went
end-of-life.
