Several machines have DVDROM readers. These are accessed just like the CDROMs, and in fact, the DVD readers also read regular CDROMs. On io, there is both a fast CDROM reader as well as a DVD reader (both located in the computer case). The CDROM is accessed through /misc/cdrom; the DVD is accessed through /misc/dvd. Other machines with DVDROM drives are aphrodite and maritimus.
