Summary: Read Failure from Gaway M675 DVD

Initial Comment:
xine-lib-1rc6a  gui reports v0.99.1

On my Gateway M675 xine does not get past the two
warnings (FBI and European).  The program reports a 

  "(Error reading from DVD.)"

I have run xine-check and everything being reported by
it is okay.  The DVD player on the Gateway is

        HL-DT-ST DVD-RW GWA-4040N

I am running Slackware 10 with what appears to be the
current version of the software.  if I switch to
running Windows XP the disk runs without a problem.

If I move the DVD to my other Linux system and run xime
from there the DVD plays correctly.  The DVD being used
on that system is 

HL-DT-ST RW/DVD GCC-4120B, ATAPI CD/DVD-ROM drive

The same xine software is being used on both system and
the OS builds are the same as well (Slackware 10.0
bare.i kernel).
In addition, the same DVD, region 1 widescreen version
of the "Passion of the Christ" is being used both
times.  The same problem has been seen with the "The
13th Warrior"

With --verbose=999 the error message only consists of

                     "]"

about the floating point exception, would you be so kind to
give us a backtrace? ;-)

i'm adding general debug make instructions that you will
need to provide a bt.

Please rebuild xine with debug information, this will help us
identifying where and why it crashed.

to rebuild xine-lib and xine-ui with debug information, unpack
the tarbal and execute the following commands:

$ ./configure
$ make clean
$ make debug
$ make install-debug

then run xine from gdb:

$ gdb xine
(gdb) handle SIG32 noprint nostop
(gdb) run

try to reproduce the crash.

Program received signal SIGSEGV, Segmentation fault.
[....]

type:

(gdb) thread apply all bt

it will print the stack trace for all threads. paste it into the
bug entry.

I have another DVD that is not region encoded that gets a
floating point  exception in libdvdnav.

  libdvdnav: DVD disk reports itself with Region mask
0x00000000.  Regions: 1 2 3 4 5 6 7 8
  Floating Point exception

The default that is in the file config in the directoru .xine is

 #input.dvd_region:1

I un-commented it and restarted xine. I get the same error
when trying to play the DVD.  After I exit zine the line is
commented out in the configuration file.

Just to be clear: I did not meant the region setting of the drive, but the 
region setting in the xine configuration (input.dvd_region). These are two 
different things, because the DVD consortium invented the region code 
enhancement (RCE), which is mentioned in the xine log you posted.

Checking the region was the first thing I checked :-)  Both
drives are running as region 1 and the disk is a region 1 disk.

ide-scsi did not make a difference with it being removed via
rmmod or booting the system and insuring it did not get loaded.

The file xine-saia.log is from the system where xine is
playing the DVD.

Two things for you to try: 
1. Compare the config entry input.dvd_region on both machines. 
2. Does the non-working drive probably run with SCSI emulation? 
  If so, try without it.
