Need to play wmv files from ftp site

We have a video production company and until we moved to dreamhost were able to post video clips on our FTP site and clients could go there click and play the file. Dreamhost will not allow the files we post to be played by our clients. Is there a way around this without going back to our other hosting companies. At any give time we may have 10 to 20 files posted that we give clients permisssion to view and play there spot.
