All this really does is remove the ASF header and replace it with the AVI header. This can cause problems if you dont have required codec.

ASF Tools 3.10

ASF Tools 3.10 are now available on StokeBloke. They can be download from here.

ASF Tools 2.30

I personally use ASF Tools 2.30. Which I have provided here ( 568K Version 2.30) to down.

This tool only removes the ASF header, as long as you have the codec they will play ok. You should then convert the AVI to a more standard codec. I normally move to DivX or Indeo. If you cant play the AVI then you probably dont have the correct codec. You should try (217K). Please see the official site and the zip file for any documentation.
