Once you install the codec packs, the movies should automatically be playable (if the pack includes the codec you need).

Have you tried VLC player?

Here's what I do: I have a program called AVIcodec (it's free). Just drag and drop your movie into the AVIcodec interface. It will tell you the specs on the movie, including frame size, frame rate, video format, and audio format. It will also tell you whether or not you have the correct codecs installed. If you do not have the correct codec, AVIcodec provides a direct link to where you can download the codec from. This program isn't limited to AVI movies. It also does MPEG, WMV, etc.

AVIcodec, a free multimedia file analyzer

By the way, have you checked the movie with Bitzi to determine if it's a valid file?
