Attached is an updated version of the patch to make VDR use
the S2API. Dominik Strasser reported that he got log entries like

  Dec  6 18:39:02 VDR vdr: [4102] ERROR: frontend 0: Das Argument ist ungültig
  Dec  6 18:39:02 VDR kernel: DVB: adapter 0 frontend 1935763502 symbol rate 0 out of range (451875..7230000)

and I now also get

  Dec  7 13:03:26 vdr2 vdr: [3441] ERROR: frontend 0: Invalid argument
  Dec  7 13:03:26 vdr2 kernel: DVB: adapter 0 frontend 0 symbol rate 0 out of range (5000000..45000000)

when trying to tune to a DVB-S2 channel.

The attached patch logs the value put into the DTV_SYMBOL_RATE slot,
and it appears to be fine. Why the value falls back to 0 when tuning
is currently totally unclear (as is the large frontend value in Dominik's

Any help in debugging this would be appreciated.

for detecting DVB-S2 (or modifiy the line using FE_CAN_2ND_GEN_MODULATION in
