Getting errors in syslog when mounting DVD


I think my config is right, but for some reason I cannot access my dvd drive from the CLI. I dont know about the GUI cause I never use it, but hopefully this is a simple problem:
fstab:
Code:
/dev/hdc        /media/cdrom0   udf,iso9660 user,noauto 0       0
output of mounting:
Code:
$ mount /media/cdrom0
mount: block device /dev/hdc is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/hdc,
       missing codepage or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so
Message in syslog as soon as I run this:
Code:
Nov 15 11:05:51 localhost kernel: [17239606.496000] hdc: tray open
Nov 15 11:05:51 localhost kernel: [17239606.496000] end_request: I/O error, dev hdc, sector 64

Nov 15 11:05:55 localhost kernel: [17239611.052000] hdc: error code: 0x70  sense_key: 0x02  asc: 0x06  ascq: 0x00
Nov 15 11:05:55 localhost kernel: [17239611.124000] hdc: error code: 0x70  sense_key: 0x02  asc: 0x06  ascq: 0x00
... And it keeps rolling! The drive is loaded and not open; I used it to install everything so I am surprised I am having issues. However, for all I know this has never worked on the CLI because I haven't really used it (it's a simple media server).

Thanks!

Use "auto" instead of "udf,iso9660" in /etc/fstab, or use the following to mount dvd:
Code:
mount -t auto /dev/hdc /media/cdrom0

Thanks. I gave it a try, but got this error. What does that mean I need to do?
Code:
mount: you must specify the filesystem type

Does this happens with any cd/dvd discs or with a specific one? Maybe you hit a known bug. Take a look here for workarounds.
