This patch was already integrated into VDR 1.3.x with some small
modifications, so VDR 1.4.0 works like that: when "optimized" tuning to
a channel doesn't get a lock within 9 seconds, a "non optimized" tuning
operation is repeated every 9 seconds until a lock succeeds.

"optimized tuning" means: when you switch from one channel to another
channel on the same polarization, there is no need to send the DiSEqC
commands. Only the tuner needs to tune to a different frequency.

So "non optimized tuning" means, that the DiSEqC commands are sent
although there is no need to. This fixed tuning issues where the DiSEqC
message got distorted on the way to the multiswitch/LNB with the result
that VDR never successfully tuned in such a case.

Bye.
