I've got the following
RedHat 7.0
kernel 2.4.0-test10
bttv 0.7.47
xawtv 3.23
XFree86 Version 4.0.1a / X Window System
(protocol Version 11, revision 0, vendor release 6400)
Release Date: 2 August 2000
(II) LoadModule: "v4l"
(II) Loading /usr/X11R6/lib/modules/drivers/linux/v4l_drv.o
(II) Module v4l: vendor="The XFree86 Project"
compiled for 4.0.1a, module version = 0.0.1
ABI class: XFree86 Video Driver, version 0.2
(II) LoadModule: "mga"
(II) Loading /usr/X11R6/lib/modules/drivers/mga_drv.o
(II) Module mga: vendor="The XFree86 Project"
compiled for 4.0.1a, module version = 1.0.0
Module class: XFree86 Video Driver
ABI class: XFree86 Video Driver, version 0.2
AverMedia TV98 Stereo
If I use Load "v4l" in /etc/X11/XF86Config-4, I get horizontal black lines at
the right hand side of the window. If I enlarge the window or make it full
screen, I get more interference -- the right hand side of the window is
unreadable.
However, if I comment out this directive, I get a better picture but I can't
really make it full screen.
Here's what turning on debugging for the bttv modules shows
/etc/modules.conf:

I'm not sure if it is significant, but I also see messages like this in
XFree86.0.log.

BTW, I did see that there was a bttv-0.7.48 and xawtv-3.24. I tried these --
the results were the same
