getting my CDRW/DVD player combo t o work howto?
 
i have tried RH9, FC1,2, 3, Debian testing, stable, unstable, and currently have CentOS 4.2 installed.

none of them have given me access to my DVD portion of my combo drive. i know it works as it works under win2k pro and winXP Pro.

what information do you need and how do i get it so i can help you help me?

Thank you.

well run the following and tell me what you get.


ls -l /dev/dvd
ls -l /dev/cdrom
ls -l /dev/hdc
ls -l /dev/hdd

that is an L, just lowercase. teh first should point at your dvd device. if it is /dev/hdc, then you might not have permissions to it, and you need to run soemthin glike;

su
password
chmod 666 /dev/hdc

to get access to it. also, you need to look into the config of the player, make sure that it is looking for /dev/dvd and make sure it is present. if you dont see a /dev/dvd, then make one. figure out what your combo drive is on, it will be the same as the cdrom, and if it is the first cd device, then it will be hdc. so, if so run:

su
password
ln -s /dev/hdc /dev/dvd

and that will create a symlink to the drive. the player wont know the difference, then you need to edit the /etc/fstab (ok that is optional, but makes for mounting things easier.)

also, if you are trying to play a dvd you need libdvdcss, libdvdread, libdvdnav, and sometimes libdvdplay installed.

Code:
[ray@ssmahome ~]$ ls -l /dev/dvd
ls: /dev/dvd: No such file or directory
[ray@ssmahome ~]$ ls -l /dev/cdrom
lrwxrwxrwx  1 root root 3 Oct 28 20:38 /dev/cdrom -> hdc
[ray@ssmahome ~]$ ls -l /dev/hdc
brw-------  1 ray disk 22, 0 Oct 28 20:38 /dev/hdc
[ray@ssmahome ~]$ ls -l /dev/hdd
ls: /dev/hdd: No such file or directory
[ray@ssmahome ~]$
does not seem to want to see my CDRW/DVD combo drive as a combo drive, just wants to look at it as a CDRW.

also so far as those codec go, if that is what they are, they do not exsist so far as CentOS yum repositories are concerned... boy do i miss debian with those codec packs.

As a test insert a DVD movie disc in the drive and type 'mplayer -dvd-device /dev/hdc dvd://'. If this works then you have to make a symbolic link that is named /dev/dvd and it is pointing to /dev/hdc. If mplayer gives you an error that it does not have read/write access, then you have to chmod /dev/hdc to 666.

Lleb_KCir 11-08-2005 12:30 AM
added a repository to yum so i could install mplayer (i normaly use kaffeine), then ran your command for mplayer. got a read error so i chmod 666 /dev/hdc as root then ran the command again, still getting the following error:

Code:

next step?

fyi, all of the help is greatly appreciated.

[edit to add] get the exact same error even as root.

shameless bump, hoping for more help.

here is some more info that might help:

how do i dump that into a file that i can post?

hdparm -i /dev/hdc

Did you place a DVD movie in your drive because the error:
Quote:
libdvdread: Could not open /dev/hdc with libdvdcss.
libdvdread: Can't open /dev/hdc for reading
Couldn't open DVD device: /dev/hdc
[file] No filename
Failed to open dvd://
Only relates to user stupidity that he or she did not insert a disc in the drive. Mplayer is a CLI not GUI, so it begins to play the media when it is executed.

Remove mplayer package file and install by source code. Package based distributions are not predictable as much as installing programs by source code.

Lleb_KCir 11-09-2005 07:27 PM
yes, have one of the harry potter movies in the drive now. when i run kaffeine it gives me a wrong media type error.

sadly, installing things from source is not something i am good enough to do yet, thus my dependancy on apt or yum.
