Ubuntu 8.04.3 breaks some codecs?

[SiKing]

Hi all.
I still run Elyssa - Mint 5. After the recent release of Ubuntu 8.04.3, I went and against my better judgement installed all level 3 updated. Several (but not all!) of my .wmv movie clips no longer play video, only audio. This is using the default Movie Player, which I actually prefer. Any idea how I would go about tracking down which package caused this?
TIA.

Is there a history in mintUpdate in Elyssa?
I think there is - you can use that to hunt down updates that could be harmful
In synaptic there is an option to force an older version - it's in the Package menu > Force version and you can use that revert the changes

I think history was introduced in Felicia http://www.linuxmint.com/blog/?p=492
I am aware of the Force version ... just which package.

I had no time to check and could not remember if it was Felicia or Elyssa that introduced history
There is no history in Synaptic and none in apt even if it may seem so if you look in the manual
Perhaps apt-get (or just apt) -u works for you - it does not for me
