This is pretty much exactly what I did:
I got the bttv stable release 0.7.101 from http://bytesex.org/bttv/ and
unpacked it using "tar zxf bttv-0.7.101.tar.gz" into my home directory.
There's no configure needed for bttv but you must have already either built
a kernel before or have already run the kernel configure script. At the
very least, cd to /usr/src/linux (or whatever the folder name is for your
kernel sources) and do a "make menuconfig" then just exit and write the
config file out when prompted.
Next, cd into the directory where you unpacked bttv and do a "make",
follwed by a "make install". If you are not root at this point, look out
for the prompt for the root password right at the end of the install process.
The bttv installation copies the newly compiled modules into the correct
places and adds some entries to your kernel config file so next time you
configure your kernel, you get the option to add in the bttv related modules.
Go back to /usr/src/linux and do a "make menuconfig". The options you need
to enable are "Character Devices->I2C Support->I2C Support" & "Character
Devices->I2C Support->I2C Bit-banging interfaces" - both as modules.
Then enable "Multimedia Devices->Video for linux" as a module and enable
"Multimedia Devices->Video for linux->BT848 Video" as a module too.
Exit, save the config file and do a "make bzImage; make modules" then su to
root and "make modules_install". Copy the bzImage file to your /boot/
directory (mine was in /usr/src/linux/arch/i386/boot/bzImage)
At this point you should have the kernel modules that you need ready to go.
You need to specify that these modules should be loaded at boot and you
also need to pass some parameters to them. Go to the bttv folder you
unpacked earlier and read the CARDLIST.orig and make a note of the card
number you are using (I have card number 10 - a Hauppauge (bt878) which I
checked with "cat /proc/pci | grep video").
I'm using gentoo linux which does module autoloading a bit different from
Redhat or Mandrake so as far as I remember (for RH and Mandrake) you need
to add the following to /etc/modules.conf:
alias char-major-89 i2c-dev
options i2c-core i2c_debug=1
options i2c-algo-bit bit_test=1
alias char-major-81 videodev
alias char-major-81-0 bttv
options bttv card=10 radio=1 #change the card number here
options tuner debug=1
Then add this to /etc/modules to autoload these modules:
..and that should do it. When you reboot, run dmesg and you should see some
kernel messages like below:
i2c-core.o: i2c core module
i2c-algo-bit.o: i2c bit algorithm module
Linux video capture interface: v1.00

Now Xawtv should run. I right-clicked after running it and set the Capture
method to grab rather than overlay and then I got a picture but mythtv
didn't need such a setting
There's a lot of detail here! If you still have problems, just drop me a
line as I'm happy to help someone else avoid the hell this put me through!!
