Thanks for your work.
I tested this with:
- linux 2.6.21-5
- Technisat SkyStar HD
- AMD Athlon(tm) 64 X2 Dual Core Processor 3800+

Tuning in general seems to be really slow. Somtimes it takes up to
to one minute for szap2 to get a lock:
zapping to 1 'Pro7HD':
sat 0, frequency = 12722 MHz H, symbolrate 22000000, vpid = 0x00ff, apid =
0x0103 sid = 0x27d8 (fec = -2147483648, mod = 2)
Querying info .. Delivery system=DVB-S2
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'

Status 0x1a seems a bit doubtfull:
FE_HAS_SIGNAL and FE_HAS_VITERBI are not set.
In DVB-S mode, I've problems to get a lock with some
transpoders at all: ZDF works with vdr, ARD doesn't .
