I had also tuning problems with my Siemens DVB-C card after I used the new DVB drivers.
I've found that the zig-zag scan is now disabled in the new VES1820 code. After enabling it again,
my card works fine (the bit error rate is a little bit high, but it was also not that low before).
I've appended a litte patch if you want to give it a try.
Cheers,
Karl
