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The data you have are outdated.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
