Windows Media Centre Problem

[cmcf]

Hi,

I've recently setup a PC with Media Centre on but have found that i need some codecs to enable the DVD Player to work and when im go to "Play Video" from a folder, as i have a few avi files dotted about.

I thought i had the correct codecs etc. as I have Power DVD installed and have also got DivX installed.

Can anyone suggest some suitable codecs that will enable Media Centre to play my DVDs and play avi files.

Many thanks
