I tried this with a few different DVDs

[Bence Ignácz (bence-ignacz01)]

Hi,

if you try running VLC or Totem as root from terminal?
Sorry if this is a stupid idea :)

[komputes (komputes)]

Bence, as a side note, VLC is not supposed to be run as root and fails if you try to do so.

Status changed to 'Confirmed' because the bug affects multiple users.

Movie Player and many other Ubuntu DVD movie player programs appear to have inadequate decryption.
