Yes, the LNBP21_PCL and LNBP21_ISEL additions did the improvement. By 
40% I mean that about 4/10 zappings between channels in different 
satellite positions are succesfull. Without this change it was very rare 
to get the dish to move, the success rate was < 1/10.

Compared to my old DVB-S card this DVB-S2 card is too unreliable for my 
family to use it. There is one possible issue with vdr rotor plugin. It 
would help in my case if it would set always high LNB voltage before 
sending gotox command and keep it for estimated time of movent (based on 
about 0.9 seconds/degree speed) before setting the voltage for the tuned 
channel. The motor movement with low LNB voltage is very slow especially 
in winter and I'm not absolutely sure that the failure is due to 
corrupted diseqc gotox command or just too low voltage to get the motor 
running. The old DVB-S card was also driving the dish at slow speed with 
low LNB voltage but I need to hack the rotor code to rule out this 
theory. I need to check also the LNB cable that connects to the PC that 
it is still OK.

OK, thanks. It seems there is now 10min fresh new code to try!
