I use VLC Media Player on my Windows XP based HTPC. It plays everything I can throw at it and, to my eyes, the quality is better than WMP.
Thx -> This made my movies look very good on the 24". The media player made it blury every few seconds. Btw, I can confirm this works under vista ultimate 64 too. Perhaps it would be good to split some stuff cause not everything will work under vista 64. (I had a mcafee unlimited version 8, but it fails to install)
