Hardcoded it to 0x61 and the results are still the same, calling szap
causes kdvb to run at 99%:

  [root@dwdsat2 szap]# ./szap -n 1
  zapping to 'hotbird6':
  sat 0, frequency = 11096 MHz H, symbolrate 27500000, vpid = 0x0000, apid = 0x0000
  using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
