This entry seems to be fine, so the frequency on transponder 1-1101
is actually 410MHz.

Was this the "one and only" NIT that was broadcast?
Meaning: did you wait for a while in case another (different)
NIT would come? I'm asking because Martin Neuditschko's case
there are several different NITs on one transponder, all with
different frequency settings, and we haven't figured out yet
how to tell which one is the valid one.

Since I have no way of debugging this here (I ave no cable)
I'm afraid you'll have to look further into this yourself to find out
where exactly something is not happening as expected.
