I have never tried to scan with the SkyStar HD.

I have the same problem. I was trying to tune to ProSieben 100 times today. And I got only 11 successful locks.
The signal strengt should be ok, as I have no problems to tune this
channel with other DVB-S cards...

Here is a little script to do such tests:

You need this szap (http://abraham.manu.googlepages.com/szap.c) and this
patch (http://www.makhutov.org/downloads/dvb/szap.patch) to make the script work.

Has anyone any ideas why the tuning failes so often? Is it a problem of
szap or the driver itself? I heard, that this card works perfect with VDR for other users...

I have not tried out VDR with the SkyStar HD. I will run some tests
during the next week.
