Comment 54 for bug 342890

I am in the same boat as AlexE. The strangest thing for me is that playing DVDs used to work just fine (without the region code set). Now those same DVDs do not work -- they play the copyright warnings and legal disclaimers and then stop with the error, "Could not open location; you might not have permission to open the file" in Totem I have tried other players too). This makes me lean towards the possibility that an update somewhere broke DVD playback on my machine.

- My region code is set properly (it matches my region and the region of the DVD's I am trying to play).
- I have the libdvdnav4, libdvdread4, gstreamer0.10-plugins-bad and gstreamer0.10-plugins-ugly and libdvdcss2 packages installed as described at https://help.ubuntu.com/9.04/musicvideophotos/C/video-dvd.html.
I checked my version on libdvdread4 and it matches the version number of the "PPA" package described earlier in the thread.
- I have tried several DVDs.
- I have tried Totem, Gxine, VLC, and Kaffeine players. All basically say the same thing (basically, I might not have permission...). Also, using strace while running Totem from the CLI, I see errors as below:

libdvdread: Invalid title IFO (VTS_02_0.IFO).
** Message: Error: Could not read title information for DVD.
resindvdsrc.c(333): rsn_dvdsrc_start (): /GstPlayBin:play/RsnDvdBin:source/resinDvdSrc:dvdsrc:
system error: Input/output error

Additionally, I get some other errors, such as:

*** libdvdread: CHECK_VALUE failed in ifo_read.c:862 ***
*** for pgc->cell_position_offset != 0 ***

*** Zero check failed in ifo_read.c:841
    for pgc->zero_1 = 0x8854

My system:
Ubuntu 9.04 Jaunty final with the latest packages
Lenovo 3000 N200 with stock DVD-RW drive.
1.5 GB RAM
Dual-core Pentium CPU

I would attach my strace log but it's 1.8 GB. Please let me know if more information is needed on this and I will supply it.

Thanks very much for your attention.
