Like many we get alot of funny little videos emailed to us. Problem is I can't view many of the movies sent. We get a message saying the The movie could not be opened Mac OS error -50.\n\nWhat does this mean? Are we missing some plug ins? If so where do we find them? These are movie.wmv format videos. I am using an intel iMac OS 10.4. Quicktime 7.2.0\n\nAny help is appreciated.\n\nFunny thing is I had no trouble viewing them on my eMac, 10.3.9.\n\nThanks.
