Thank you for contacting us. WMV files have known compatibility issues on some browsers, such as Chrome Browser. This may be related to your issue. Converting the format to something more popular such as .mp4 may correct your problem.
Each time I Cmd+S an .mp3 or .mp4 file, it saves it, but as it turns out, as an empty Zero bytes file. Even if I'm explicitly choosing Save As and Format=Page Source, it doesn't work. I doubt this is an expected behaviour as it has let me down several times since some of the files are no longer online. 041b061a72
