SWF Helper

I may be wrong but I don't think the SWF Helper plugin displays anything in the viewer pane. It's just for thumbnails.

The ActiveX Document plugin displays flash files in the viewer pane but can't handle FLV.

As far as I can tell there isn't an ActiveX control for displaying FLV files since if you drop a FLV on Internet Explorer it won't display it. It seems they have to be turned into a Flash .SWF file to be playable.

I'm not an expert on Flash/FLV, though, so if anyone has information on how a program could display FLV files then please pass it on. I'd quite like to be able to display stuff saved from YouTube as well.

Edit: (Months later.) We now know how to make FLV play in the viewer pane. See the FAQ: Some movie/music formats don't play in Opus for help.
