[orca-list] playing videos in ubuntu

[Michael Weaver <weavermicha googlemail com>]

I have unfortunately had to go back to Ubuntu as for some reason each 
time I have to do a fresh install of Sonar I seem to have problems 
getting first updates and I think the last times I tried Sonar it had a 
problem checking certain servers so I am wondering if this was the 
problem with updating properly.
The main problem I am having with Ubuntu seems to be using video codecs 
to play classic DVDs.
I just tried to play a DVD after installing the ubuntu-restricted-extras 
codecs and VLC Media Player but when I launched VLC I got the following 
error message even though I obviously do have an internet connection 
which I have used for downloading emails and doing updates so it is 
strange I am getting this.
Data files for some packages could not be downloaded

The following packages requested additional data downloads after package 
installation, but the data could not be downloaded or could not be 
processed.

ttf-mscorefonts-installer

This is a permanent failure that leaves these packages unusable on your 
system.  You may need to fix your Internet connection, then remove and 
reinstall the packages to fix this problem.
How do I resolve this?
