In that case, something like:

mount -t cd9660 /dev/acd0c /cdrom

should work.

Reasons why it may not include:

	a) it's not a iso9660 filesystem (but if it's mounted on a linux
	   box as you say, it is)

	b) your cdrom isn't /dev/acd0

	c) your kernel doesn't have support for iso9660 filesystems
		(I'm not sure what error message you'd get then)


You can eliminate b) from the above by running something like 
"dmesg | grep -i cd" (but only if the machine has been rebooted recently
enough for the data to still be there.  The results from one of my
machines is:

mike at lir:~$ dmesg | grep -i cd
acd0: CDRW <Memorex Twelve MAXX 1032> at ata1-master PIO4
GEOM: create disk cd0 dp=0xc47f3e00
cd0 at ahc0 bus 0 target 4 lun 0
cd0: <TOSHIBA DVD-ROM SD-M1201 1R08> Removable CD-ROM SCSI-2 device
cd0: 20.000MB/s transfers (20.000MHz, offset 16)
cd0: cd present [1135840 x 2048 byte records]
cd9660: RockRidge Extension

>From this I can see that I have 2 "cd" devices:

a Memorex Twelve MAXX 1032, which has the device name of acd0, so I
should use /dev/acd0 or /dev/acd0c to mount cd's in it.

a Toshiba DVD-ROM, which has the device name of cd0, so I should use
/dev/cd0 or /dev/cd0c to mount cds or dvd's in it.


Could you try the above, and if it doesn't work:

	a) tell us the result of dmesg | grep -i cd
	b) cut'n'paste the command you ran to mount the DVD, together with the
error?  (it's probably a good idea to cut'n'paste it, so that subtle but
important transcription errors don't creep in).

Cheers,
Mike
