We changed the tuning because for many people the tuning in 0.18.1
caused a lot of zero length recordings. Search the dev archives for
all the iterations we went through. The current tuning works for
most DVB-T people, but does not yet work well for DVB-S people.
The remaining problems in DVB-T are with the Nova-T DVB driver.

The Nova-T DVB driver hasn't been fixed yet. Until it is, I can say it's broken :)

Actually this will be getting a little faster in SVN after we finish
refactoring the EIT scanner...

Have a read through the archives, look for Aafloy's posts.
The code in question is in dvbchannel.cpp, mostly in the
wait_for_backend() function.
