Title: DVD-ROM Setup Problems
Post by: LorKorub on 11 December 2002, 01:41

I followed the steps in the DVD-HOWTO that was included in Debian, but I am having some trouble.

First, it said that I needed to have a kernel with UFS and UDF support. It also says I needed MTRR (which is included.) So I compiled a new kernel (2.4.20)  and built in both UFS and UDF during Xconfig. When I do a modprobe on UDF, it can't locate it. UFS checks out, but UDF is not listed anywhere in lsmod.  

I tried editing /etc/fstab to switch the DVD drive's FS to auto, but when I try to mount a DVD it says 'No Medium Found."

Any suggestions?

What steps did you perform, exactly, when you compiled the kernel?

You will only use UDF if you have a DVD RW with packet mode writing.  My DVD drive works, and I do not have either UFS or UDF support at all.

I'm using 2.4.18, and I did not recompile it when I put the DVD drive in.

I recompiled the kernel with all of the same stuff I had on 2.4.18, but just added UDF and UFS. I didn't add UDF read and write, just UDF read (the write was labeled Dangerous so I didn't install it.)

I had a problem installing the LiViD utilities as well.  It couldn't find Glib, even though I know that I have it installed. Maybe that is part of the problem?

What do you have in /etc/fstab for your DVD drive?  Maybe if I could get a look at that, it would help solve my problem.

err,what kind of dvd is it?
i thought that things like movies were raw info. and like had to be  read raw. like mplayer /dev/dvd would play a dvd/*only if the symlinks are in place though*/

I don't know if this helps but my DVD is called a CDROM, in fact if I try to mount /dev/dvd it tells me there is no such device. I had to change the ogle config to look for /dev/cdrom so I can play DVD (not properly but that may be a hardware prob., and mplayer doesn't yet play DVDs for me).

I am trying to play a movie..Donnie Brasco to be precise.  

I made a sym link from /dev/cdrom to /dev/dvd so ogle would be able to see it but still, nothing. Here is the error message I get:

I can't open it in Xine either.  In Xine, you have to mount the DVD first, but every time I try that I get the "No Medium Found" message.

That is very similar to the error I got with ogle. I vim as root the oglerc file (I forget exactly where it is, can post tonight when I get home to my machine). And about 15-20 lines down there is a line the states dev=/dev/dvd or close to that. I swapped that to /dev/cdrom and it played.

And just to be dumb here you do have libdvdcss and libdvdread installed (you get them at the ogle site) don't you? Just noticed there is a later version of libdvdcss. It's 1.2.2.

I haven't got to symlinks and things yet so I'm just editing at the source.

I think it's to do with the way especially earlier dvd players were designed as DVD/CDROM combo.

Both /dev/dvd and /dev/cdrom should be symbolic links to the drive.  In my case, /dev/hdb.
