usb DVD RW problems


Hi All,

I bought my daughter a DVD RW for Christmas. It's an external usb model. She's running Fedora Core 1. The computer recognizes the drive and after mounting it, fstab is seeing it as /mnt/cdrom2. She does have two IDE optical drives, cdrom (CD ROM) and cdrom1 (CDRW).

I have no experience with DVD or USB in any OS, so I really don't know what to see or expect. Anyway, I put a DVD in, opened gmplayer and tried to play a DVD. The error message I got was "unable to open IFO file" or something very similar to that. I'm at work and can't get the exact messages right now.

Nautilus was able to browse the CD and read the files, but of course not play the movie. Do I need to edit the fstab or mtab or some other file to get it to recognize the drive as a DVD? I did do some "googling" and searched the Red Hat discussion list for references to DVD's and USB, but really didn't even know quite where to start, so was unsuccessful.

I'm not a total Linux newbie, I just have no prior experience with DVD's or usb on computers.

TIA for any pointers.

Jim Dishaw

please post the output of "cat /etc/fstab"
it wouldn't be a big problem if you can see what's on the disc and your graphics card was working properly.

You will need to configure gmplayer to point to the DVD player. The device is proabably /dev/scd0

Thanks for the responses. Actually, fstab is seeing it as /dev/cdrom2. My fstab is:

Quote:
[dishawjp@eunix dishawjp]$ more /etc/fstab
LABEL=/ / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
none /dev/pts devpts gid=5,mode=620 0 0
none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0
/dev/hdd3 swap swap defaults 0 0
/dev/hdc3 swap swap defaults 0 0
/dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0
/dev/cdrom1 /mnt/cdrom1 udf,iso9660 noauto,owner,kudzu,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,owner,kudzu 0 0
/dev/hdd2 /rh9 ext3 noauto 1 3
/dev/cdrom2 /mnt/cdrom2 udf,iso9660 noauto,owner,kudzu,ro 0 0
/dev/cdrom is the IDE CD ROM, /dev/cdrom1 is the IDE CD RW, and /dev/cdrom2 is the usb DVD RW.

I'm guessing that most of the problem is that fstab is mounting the device as a CD ROM instead of as a DVD. Should I symlink /dev/cdrom2 to /dev/dvd or something like that? This is my daughter's computer and I don't want to do something to hose it and not have time to straighten it out before she heads back to college next week.

Thanks again,

Jim Dishaw

you need to do "ln -s /dev/cdrom2 /dev/dvd" as root and it should be fine now for playing movie.
just do "mplayer dvd://" after you mount "mount /mnt/cdrom2"

Thanks tricky_linux,

I appreciate the assistance, and I created the symlink, but still no-go. Here's the error message... maybe you can make something out of it.

I have used mplayer to play .avi CD movies before and don't understand why I'm getting some of these error messages.

Using a slightly different command (gmplayer dvd://) I got the following:

how come you are using the cvs version?
uninstall the whole thing by using
$rpm -qa | grep mplayer
to see what did you exactly install and uninstall using "rpm -e <package's name, without the rpm extension at the end>"
go to http://www.mplayerhq.hu/homepage/design6/dload.html and download an official released version with was v.1.0pre3 right now. I am using 1.0pre1 and it works every time i reinstall my rh 9.0.
never use the cvs version if you are a newbie. because the cvs version was for those who knows what exactly what they are doing and they can debug it by themself. unlike us.
