If you have some videos in ASF format and you do not have any player that can display them correctly because it does not have the necessary codecs (either video or audio) then a good solution is ASF to AVI Converter 3.1 which converts the ASF videos to the format much more compatible with AVI and so you can see them on any player you have.
The user can configure the characteristics of the resulting video: Size, ratio, compression level, etc., converting not only ASF format but also from WMV, MPEG, MPG, VCD, SVCD and DAT directly to AVI.
For its correct operation you need to have previously installed DirectX 9.0 or higher, if you do not have them you can download them by clicking on this link.
