My setup is somewhat similar, while it may be hard to figure out which
scsi device is your media player, in fact, it is just another scsi
device in the naming scheme, maybe try some out. Udev & pmount is
supposed to take care of this issue, (I haven't used it yet) there is a
config file that teach item has an entry based on the manufacturers
data so it can mount each item the same way when plugged/unplugged.

Peace
