I can watch most DVD's on my machine using VLC but today, I went to watch Thor, and it won't play.

• libdvdread4 and libdvdcss2 are at the latest versions.
• vlc -v returns 1.1.4
• w32codecs are installed and reinstalled
• ubuntu-restricted-extras are same as above

My machine recognises the disc and I can open the folder and browse the assorted .vob files, of which there are many. None of them will open in VLC, or in MPlayer etc.

When I run vlc -vvv /media/THOR/VIDEO_TS/VTS_03_1.VOB I get:

File Reading Failed VLC could not read the file

I also see command line output like this:

[0x963f47c] main filter debug: removing module "swscale"

This happens with onboard and Known Good USB DVD player I don't have standalone DVD player to try with TV

I am going to watch another film instead for now, because I can do that. I just can't watch THOR, and I'm pretty confident that the disc is ok. It is a rental, but it's clean and there are no surface abrasions. I even cleaned it with Christian Dior aftershave to make sure.
