Jon:

Perfect! Here is what I did based on your suggestion and it seems to have
worked:

Downloaded the CVS versions of dvb-kernel and video4linux
# cd /home/mythtv
# cvs -d :pserver:anonymous at cvs.linuxtv.org:/cvs/linuxtv login
Hit enter when it asks for password
# cvs -z3 -d :pserver:anonymous at cvs.linuxtv.org:/cvs/linuxtv co -P
dvb-kernel
# cvs -d :pserver:anonymous at cvs.linuxtv.org:/cvs/video4linux login
Hit Enter when it asks for password
# cvs -d :pserver:anonymous at cvs.linuxtv.org:/cvs/video4linux co -P
v4l-kernel

Go to /home/mythtv/v4l-kernel/linux/drivers/media/video/ and copy all
content except CVS folder into /usr/src/kernels/2.6.13-
1.1526_FC4-i686/drivers/media/video/ directory (this will copy the bttv,
video-buf and other files into my kernel sources directory).

Applied my patch to the av7110 c file in the dvb-kernel directory.

# cd ./dvb-kernel/build-2.6

Commented out lines 15-18 (since it was the bttv driver which was causing
problems, and I didn't need it since I am using Nexus-s):
15 # ifneq ($(CONFIG_VIDEO_BT848),,)
16 # export BTTV=yes
17 # endif

# make
# rmmod ... - to remove the existing DVB modules (which came as a part of
the kernel)
# ./insmod.sh load

After that, the new driver seemed to get picked up and everything works.

Now, a final question for you: Do I need to do anything special to load
these newly drivers automatically upon reboot (like put something in the
modprobe.conf file, or did the .insmod script take care of that already)?

Thank you very very much!
