lovejoy: I think you chose a misappropriate location to post! Your topic has nothing to do with the original thread posting. doh! My guess is you've downloaded a wmv file. I see no no logical reason why a mac user would pursue downlding wmv files. wmv files are very prone to licencing, links to advertising, links to highly questionable sites that record your ip address, etc. My advice is stick to avi & mpeg/mpg & mov/moov files.
