This is one of the problems I am having. With zigzag enabled or disabled
it sometimes looses lock and doesn't seem to be able to get it again. But
this happens both with zigzag and without zigzag. I was wondering
maybe after loosing sync a few times the driver could reset it self
as you said.
Maybe you could find out what really happens when you drop
lock and try to fix that?
With my (yes, broken, yada yada) DVB-T card I could get a bad
lock even when tuned slightly off, which mean that if
the zigzagger thought it had a signal drop it could start to
zigzag, find the carrier on a less than optimal frequency,
and stay happy with that.
When I turned the zigzagging off the demodulator handled any
deviations just fine (if there were any), and I haven't seen
any problems because of the lack of zigzagging.
My experience with this is obviously very limited, but I am
still not convinced that zigzagging is necessarily the right
thing to try with DVB-T when you have the exact frequencies
and with a frontend that does minor corrections automatically.
Maybe one could change it to no try to retune to a frequency
that would only make the demodulator do its best to correct it.
For other situations I have no idea.
