DVD Problem

DVD Problem

[Christian Hilgers]

Hi,

I'm trying to use the 2.4.1 Kernel but I have some troubles with my
ATAPI Matsushita UJDA510 DVD (Intel 82371AB/EP PCI Bus Master IDE
Controler).
It works perfekt with CD-Rom but when I try to read a ISO 9660 DVD I got
an error.

I can mount the DVD and I can list the complet content but I guess I
can't access any File behind 650 MB.

e.g.

mount /cdrom
$ cat /cdrom/blah/blah/INDEX
cat: INDEX.german: Input/output error

The kernel log
Mar  3 18:45:06 laptop kernel: VFS: Disk change detected on device
ide1(22,0)
Mar  3 18:45:10 laptop kernel: ISO 9660 Extensions: RRIP_1991A
Mar  3 18:46:05 laptop kernel: attempt to access beyond end of device
Mar  3 18:46:05 laptop kernel: 16:00: rw=0, want=2855480, limit=1052700

It also works well with a 2.2.14-SuSE Kernel.

Any hints.

Thanks
Christian

So you need to compile the kernel with UDF support , which is the
filesystem used in DVDs. As you said, iso9660 works, but only for the
first 650 mb. And after it take a look at www.linuxvideo.org and
www.videolan.org.

UDF was the first I tried, but it didn't work.

I tried Kernel 2.4.0, this one is also working fine. Than I used the
same .config for the 2.4.1 Kernel.
And the DVD did't work!!
Maybe a bug in the CD-Rom driver?
I think I will try the 2.4.2 Kernel.
