FLV files require a splitter because of the way it encodes two streams. So if you want to do a search, FLV splitter will get you closer to what you are looking for. Here is a good link for how to install one: http://www.afterdawn.com/guides/archive/how_to_play_flv_files.cfm
I usually install the klite tools mega pack for all my codecs that I use and then this splitter file and I have no problems with most media file types.
