Attached is a patch which adds some output to the tuning process.

Legend:
t: current time in seconds
c: card index
r: result of action
a: action in the tuning code
-: start tuning
~: failed tuning (didn't locked)
=: succeeded tuning (locked)
As you can see in the above output, VDR tunes card 0 to some channel and
after 60 seconds, the EPG scan starts using card 1. After 20 seconds, it
tunes to a different transponder on the same "band", so there is just
FE_SET_FRONTEND reported.
I'll now add the same output to szap.
Bye.
