Welcome willie8868,

I don't know of CODEC probs with audio files in WMP. So my guess is you're trouble is with videos. To use WMP for newer videos, you'll need to download and install a new CODEC pack (I use download.com). Or, you can install another player, such as VLC, that has all CODECs installed.

If you're having a problem with bogus files, you can save yourself time and trouble by using the Bitzi link to obtain file info before downloading.
