I played some flv files fine under 0.8.4a. Then I uninstall and install 0.8.5 and only 1 file played. Then I remove and re-install 0.8.4a and it doesn't play flv files anymore. I repeat the uninstall/install with 0.8.4a and 0.8.5 for a while then I say let's restart the computer after uninstall VLC....
