Codec question

[Patton Echols]

When I first installed ubuntu edgy I went through a number of steps to 
get media files playing correctly.  I have now ubgraded to feisty (a 
month or two actually) and just recently discovered that several .WMV 
files won't play  correctly.  They used to work.

I found instructions for w32codecs here:
http://ubuntuforums.org/showthread.php?t=413624

That has instructions for getting w32codecs from Medibuntu.  I did not 
follow that procedure exactly because Medibuntu is shown as enabled in 
synaptics package manager "third party software" even though I don't see 
it listed in /etc/apt/sources.list  also, an attempt to install 
w32codecs returns the following:

$ sudo apt-get install w32codecs
Password:
Reading package lists... Done
Building dependency tree      
Reading state information... Done
w32codecs is already the newest version.
The following packages were automatically installed and are no longer 
required:
  libflac++5c2 libgnet2.0-0 ntp-simple ntp xlibmesa-gl-dev
Use 'apt-get autoremove' to remove them.


So two questions, (1) is there another version of w32codecs that I 
should have? 
(2)  Is there some reason I should not remove the packages as suggesteb 
by "apt-get" above?


Thanks in advance for any and all thoughts.
