18 Alpha TC3 DVD defaulting to networked install

[Andre Robatino]

The 18 Alpha TC3 DVD appears to default to a networked install (meaning it uses
packages from the updates repos when they are newer than the ones on the DVD). I
noticed this when choosing the GNOME Desktop and nothing else, and ended up
getting "Software Selection" errors. Clicking on "Error checking software
dependencies. Click for details." gives

1:control-center-3.5.5-2.fc18.x86 64 requires libgnome-bluetooth.so.10()(64bit)
shotwell-0.12.3-1.fc18.x86_64 requires libgphoto2_port.so.0()(64bit)

even though shotwell is not even on the DVD and the repoclosure problem with
control-center was fixed on the TC3 DVD. I looked under "Installation Source"
and there is a box "Don't install the latest available software updates. Install
the default versions provided by the install source above." which is unchecked
by default. I checked the box, but still get the same errors, so it's not
working. Aside from that, I'm not happy with the default of a networked install
in that

1) It's less reliable than a non-networked install because of problems like the
one above (assuming the DVD itself has no repoclosure or file conflicts
problems), and

2) It means higher bandwidth use, since the default is to download updated
packages in full, rather than installing the old version from the DVD and then
saving bandwidth by downloading the updated version with yum-presto.
