Several channels in Italy are marked as if they are using 8MHz for VHF (the auto-Italy is
the most weird one, as it defines all VHF frequencies with both 7MHz and 8MHz).

Well, auto-Italy is a superset of the it-* files. For example "T 177500000 7MHz" exists in some files (Modena, Montevergina) and "T 177500000 8MHz" in others (Sassari), so both possibilities have to appear in auto-Italy (similar for other VHF frequencies, it simply doesn't seem to be regulated). There's nothing to fix there, auto-Italy exists exactly because of these irregularities.

Hi Christoph,
since June 2009 all VHF channels in Italy use the European canalization, which means there is no 8 MHz VHF channel anymore.

The data you have are outdated.

If you need some reliable reference to know what is broadcasted in Italy, the best available source is this amatory website:

http://www.otgtv.it/index2.html

It is maniacally maintained by a single person, which is a real enthusiast of TV broadcasting and has access to reliable first-hand informations. There are also a few institutional websites, but they can not compete with this site in terms of accuracy.

The auto-Italy table for DVB-T should be just:

VHF:
channels 5-12 with 7 MHz bandwidth;
UHF:
channels 21-69 with 8 MHZ bandwidth;

The last 6 regions will switch-off analog broadcasting in the first half of 2012 (Abruzzo, Molise, Puglia, Basilicata, Calabria, Sicilia). Until then, there are a few analog channels using some weird frequency table, but all digital multiplexes are already converted to the new European frequency table.

Best,
Gianluca
