Hello Denis,

This looks like a really old version of the driver.  I would suggest
you start by install the latest v4l-dvb code and see if it works.

http://linuxtv.org/repo

If it doesn't work, then repost to the mailing list including the
updated dmesg output (which includes more debugging than the older
version).
