Unfortunately, "fully wired" does not tell anything about the screening,
or the quality of the cable. :)

Yes, even then. When you're viewing some other program source than the
built-in tuner, the tuner will usually just stay active on the
background, on the channel that was last selected, and the tv set will
provide that signal through the "video out" pin of the SCART socket, all
the time.

The tv set might not do this with _all_ SCART sockets, though. (If there
is only one RGB-capable SCART-socket, the tuner's signal will typically
be output through that one.)

You can actually test this by connecting two tv sets together, with a
fully wired SCART cable. Use the same SCART socket which you're now
using for your DVD player at your tv's end. If you now switch both tv
sets to the AV "channel", respectively, you should see the picture from
the _other_ tv set's tuner on each.
