Since you confused us all I couldn't answer correctly.
WMV files will play in Hoster. How are you adding them into Hoster?
Try adding from the Main screen by clicking on the video button. This will tell you if they work or not.

If you add them from the "Import from Hard Drive, then you need to have those files in a folder somewhere and plan to leave them there. Hoster will create a separate second file (256 byte) with just the header in it. Both files must be present in the same location for Hoster to be able to play them.
