Pedro,
Ubuntu 10.04 fully updated still can't read a DVD.
The default movie player searches for a plugin (DVD source) but does not
find it.
So Bug 483211 is resolved, but the OS still won't read a DVD.
Don't the developers test this kind of basic functionality before letting
the product go out
Thank you for taking the time to report this bug and helping to make
Ubuntu better. A new version of GStreamer is available in both Lucid and
Maverick and we are wondering if this is still reproducible in any of
those versions, May you please test and give us of feedback about it?
Thanks in advance
