I don't know what hermann meant, but different hardware copes differently
with configuration file errors. One of my tuners refused Melbourne's
digital channel 7 even though the other worked - until Kaffeine's
configuration was corrected, then they both worked.
Are you worried about the output of Zap, or the contents of a master
configuration file somewhere?

I think that the important change was guard interval (in Kaffeine) from 1/8
The nearest thing that I can find that looks like an authoritative source
about what Australian broadcasters were using in 2003 is
<http://www.dba.org.au/index.asp?sectionID=120> which says that the correct
guard interval is 1/16, but it also says that things can change.

Have you got any specific questions?
