Need help to get Tevii S471 running

Hello dear all,
i have buy a DVB-S2 card from Tevii S471 and i need help to get it running with Debian Wheezy/Sid Kernel 3.2.0-2-686-pae.

The Tevii S471 was similar to the Tevii S470 but it has different LNB control.

The first thing I have to use the s2-liplianin drivers unfortunately I was not successful. s2-liplianin:

Next, I have made a git clone from media_build and change the files (cx23885-dvb.c, cx23885-cards.c, cx23885.h) with code from s2-liplianin. See the diff output at the end of this message.
The compiling was now ready and i have installed the new driver.
It was loaded and the adapter0 was installed.

A scan with w_scan (w_scan -fs -s S19E2 -X > channels-sat1.conf) give me some errors like this:
(time: 00:11) diseqc_send_msg: FE_SET_VOLTAGE failed.
diseqc_send_msg: FE_SET_VOLTAGE failed.
But it found some but not all Channels it is a problem to switch the LNB.

A test was successful with Mplayer and a scanned channel (mplayer dvb://ZDF) unfortunately the picture and sound output was disturbed.
After a restart and a new scan it found new channels but the card dont switch to the older channels.

Many Thanks for reading this message, hopefully
