Description:
Kubuntu Dapper Flight 5 Up2Date

Well. I'm trying to read a DVD. So got it in reader: Window plops
proposing to read it with Kaffeine. OK.

I got two errors (exactly the same errors with menu entry : "Read DVD")
------------------------
The source can't be read.
Maybe you don't have enough rights for this, or source doesn't contain data (e.g: no disc in drive). (system:/media/hdc)

Then
-----------------------
No plugin found to handle this resource (dvd:/)
-----------------------

[Details] give me that (not translated in french indeed):
-----------------------

So I see nowhere the fact that I have to install something.

I personnally know I should get the libdvdcss2 (or any of DeCSS
implementations) from some obscure website, but I think that the
information the program gives to user is insufficient.

I am very clear about illegality of the libdvdcss2, but is it illegal
for Ubuntu to just "mention" it ? Or at least "make allusion to" like in
"you should install the appropriate program" or redirect the user to an
explaining website (somewhere on Ubuntu.com ?)...

I think that issue should be intensively discussed, because the user is
limited without knowing (or understanding) why. If Ubuntu intends to be
"all public", it has to be a little less obscure, isn't it ?

P.S. Maybe the answer is in the first error : "Maybe you don't have
enough rights for this (...)2
