Hello,

Tuning with the "Twinhan Magic Box" do not work with the dvb-t driver of
the official Linux Kernel 2.6.18, 2.6.18.1, 2.6.18.2 and some 2.6.19-rc.
For example: tzap do not get a lock while tuning but it should get a lock.

Last dvb-t driver which worked was in 2.6.17.14.

Now I use Linux Kernel 2.6.18.2 with the external driver which I
received with the command "hg clone http://linuxtv.org/hg/v4l-dvb".
That works.
How I did it in detail: http://gentoo-wiki.com/TwinhanDTV_Magic_Box

My question: When will the dvb-t driver in the official Linux Kernel
work (= is able to tune) again?
I do not understand, why it do not work since so many Kernal releases.
Do nobody recognize this bug? I thought the dib3000 chipset is popular?!
