I just reinstalled QW under Linux the other day. There are 2 installers. There's a 'full' installer which will copy all of the data from the DVD. There is also a smaller 'nomedia' installer which requires you to copy the data from an existing Windows install.
Exactly. But the v1.4 Release Candidate is only awaible as a nomedia update currently. The full v1.4 update will have, like the v1.2 update now already has, an option to install from the DVD.
