DRM means they are protected to only play in the player they were imported or downloaded to. WMV is a WMP specific file format so yes they would play in WMP. Doesn't mean Hoster shouldn't play them.
It sounds like Hoster encountered a problem reading the file and recognizing the format. The ones that don't play, do you know what the original date is of the files?
Also which K-Lite codec pack did you download? Is this for the Windows 7 64 bit computer? There is a special one for 64 bit too.
