I guess the title pretty much says it all. When I open one of the files a dialog box comes up that says, "Additional software is required for quicktime to playback this media" with a link to the quicktime components page. If I just play the file anyway the sound is all garbled and there's no video at all, it just stays black. Also, the same exact thing happens with realplayer. does this mean there's a problem with the files or something? Thanks.
