Mounting DVD disk

[Tony K.]

Yes, that helps.  I found the line in the /var/log/messages for the DVD,
mine is hde.  I was able to mount a commercial DVD movie, but when I try
mount the DVD data disk it tells me that I must supply the file system:

[root]# mount -t auto /dev/hde /mnt/cdrom
/dev/hde: Invalid argument
mount: block deveice /dev/hde is write protected, mounting read-only
/dev/hde: Invalid argument
mount: you must specify the filesystem type

I tried also viewing this data DVD disk with MacOSX.  It will mount, but
it shows it as empty.  Perhaps there is a problem when it was burned.  I
believe it was burned on a Win(XP?) machine and I am not sure what
standard of DVD was used, i.e. DVD(+/-)...
