Since we are going to be forced to deal with .flv (Flash Video) files, I think it might be good to discuss what method works best for converting .flv to another format, what program to use for that, and also what player(s) are best for raw .flv playback. Personally, I like to use GOM Player for playback since it's the only one I've found so far that allows both full-screen playback *and* (most importantly) the ability to skip through the file to any point of playback, something that VLC Player doesn't do (it quits if you try).
May I just reiterate how much I hate Flash video content?
