No master or slave doesn't matter I just think they pointed out
that target0 is the same as Master in the ide controller and
target1 is slave.
But the are using /generic instead of /cd, that might be the problem.
Are you running ide-scsi on the dvd device?

The best is if your dvd drive is region free otherwise the keys will
be cracked by libdvdcss.
Ogle in itself doesn't care about the region (well you can set the region
in the oglerc file if the dvd checks it).

This must be the wrong device we are trying to use.
It shouldn't say : No medium found, when you have a dvd in it.
Maybe you should try /dev/ide/host0/bus1/target1/lun0/generic

If that doesn't work you can try the other ide devices also like
bus0/target0..., bus0/target1..., bus1/target0...

I'm not using devfs myself so I'm not sure which device is the correct
to use, maybe there is another device when you are running ide-scsi.
try the dvd_test program on your cd-rw drive also with a disc in it.
It should at least report something other than No medium found.

Anyone else that is running devfs that could help?
