IIRC I added the retransmissions because switching was not 100%
reliable (with driver 0.9.4 and vdr 1.0.4, long time ago).
As I don't have a logic analyser, I was never able to track down the
real problem. Anyway, Eutelsat recommends to repeat the sequence, and
it increases reliability, so I never changed it...

@Klaus:
Please change the "Optimized for full DiSEqC" sequence in diseqc.conf
of the vdr tar-ball, because some frontends do not turn on LNB power by
default.
