Getting DVB Working

Hi,
I'm at my wits end trying to get my Nova-t DVB-t card working with mythtv.
I'm running Mandrake 10.1 community and I've upgraded the kernel to
2.6.9-rc4. I've patchde the kernel with the patch from the bytesex website.
That all seems to be working but I don't have a /dev/dvb directory for
DVB-apps to work with. I've attached a lspci and lsmod readout and would be
eternally grateful if someone could give me some pointer on how to proceed.

Many thanks
Tom

RE: Getting DVB Working [In reply to]

Attached script is from linuxtv.org; it will create your DVB devices
assuming your are not running devfs (there is no file called /dev/.devfs).

Run the mythtv setup program and go to capture card and select DVB type. It
should be saying something like "No file or directory" at the moment as its
error code. Run the shell and try setup again. If it says something like
"Permission denied" you need to fiddle with the permissions on /dev/dvb/...
If it says something like "Cannot open device" then you have to find a
working kernel version ----- something I'm in the middle of now since my
original mythv load crashed over the weekend. I have had most success with
the 2.6.5.531 build that comes with FC2 but am trying other builds.

Try this (from dvb-driver):

if [ -e /dev/.devfsd ]; then
echo "It seems you are using devfs. Good!"
exit 0
fi

# get rid of old DVB API devices; do it twice for good measure...
