Installing the driver breaks DVB-T adapter.

I'm assuming that you using a current media_build tree from http://git.linuxtv.org/media_build.git? If so then follow the README therein and

Code: Select All Code

./build --main-git

That should checkout the current linux tree into media/

[JeroenM]

I think i am ready to give up. I tried it two times now.
running ./build --main-git did indeed create the media directory under media_build and your excellent guide makes much more sense.
I removed the whole media_build directory both times and ending up with the same result below.


This is the exact procedure i did both times:

Code: Select All Code

git clone git://linuxtv.org/media_build.git
cd media_build
./build --main-git

wget http://www.softsystem.co.uk/download/tbs/tbs698x-2.6.38.patch
cd media
patch -p1 < ../tbs698x-2.6.38.patch

DRVR="linux-tbs-drivers_110806.rar"
wget http://www.tbsdtv.com/download/common/$DRVR
mkdir tbs && cd tbs
unrar x ../$DRVR
tar -axf linux-tbs-drivers.tar.bz2
cd ..

cp $SRC/tbs6981fe_driver.o.$ARCH $DST/tbs6981fe_driver.o
make

I can´t believe it has to be so incredible problematic to get the two differnt cards to work at once.
It is driving me nuts.
Thank you very much for helping me out, Lawrence.

I would recommend giving up on the media_build tree - it looks too problematic. I've actually built a custom Linux kernel with the modified drivers:

I'm off for the next week so best of luck with this.
