Preferably stay away from codec-packs and install individual codecs/filters instead.
As mentioned in item
(4) of my Help2Help-post (a.k.a. "
READ THIS FIRST BEFORE POSTING")
see
adicoto's list of codecs.
(or use search to find e.g.:
http://bsplayer.com/forum/viewtopic.php?p=23187#23187 )
(You need to be logged in for
adicoto's list with download-links.)
P.S.:
Did you already take the trouble to read my Help2Help-post?
