Nobody has ever provided any more information about this problem, other
than the information in the links above.  I would like to be able to solve
this for you, but I do not know the answer.  Instead, I can offer a

If you are unable to build the v4l-dvb modules from the linuxtv.org hg
repository (howto - http://linuxtv.org/repo) against your fedora kernel,
then there is another option.

If you are using the ATrpms package repository, then simply do:

yum install video4linux-kmdl-`uname -r`

...That will install the latest snapshot of the v4l-dvb kernel modules
into your running fedora kernel.  I cannot make any promises that the
2.6.18 tree will ever be fixed for your device, because I do not know
what is actually causing the error... but this method should hold you

If you want to help us to find the actual problem that caused this
behavior, please do a git bisection test to determine the problem
changeset in kernel development history:
