Well, i had the same problem and the solution is more easy than you think: 1.- click on next link http://www.dll-files.com/dllindex/dll-files.shtml?quartz 2.- click on the download quartz.dll file. 3.- download quartz.dll file 4.- go to explore on your windows system and change view files the way you could view dll files. 5.- go to c:windowssystem and delete quartz.dll file (yes, do it, there is no more problem) copy quartz.dll downloaded file. 6.- it's ok! Now you can view mpg and avi files. I donĀ“t know if wmv files work that way.
