I wish that Finder show video thumbnail for all kind of formats and containers. *.flv doesn't get a preview, some *.mp4 not, *.mov not.
Is this possible? Maybe a video browser in place of Finder? I have Perian installed.
I didn't find any way to add support for mkv or other formats. VLC, MPlayerX, Movist, and NicePlayer don't come with Quick Look plugins.
