--- Comment #12 from Rosanne DiMesio dimesio@earthlink.net 2012-02-20 08:18:52 CST --- I just tested a clean install of Powerpoint 2003 in 1.4-rc4, and was able to insert and play an mpg file without installing WMP at all, though the video was somewhat off-center. Inserting an avi file produces an error message if WMP is not installed, but they insert and play fine here if it is installed. I don't have any wmv files to test.
I had to install WMP10 rather than 9, because winetricks wmp9 gave a cryptic error message.
It does need the required gsteamer codecs installed (IIRC, "bad" and "ugly").
