On2 Flix Pro does a double pass rendering and saves to FLV or SWF. This reduces the file quite a bit.

174mb is quite big for any video shown on the Web. You might get to half that with On2 Flix, but I doubt it.

I use On2 Flix Pro because I can make it preload, it has it's own players and you can make it streaming if you have your own server or access to a streaming server.

It's on sale now, but I think only if you own On2Flix Standard. Like 100 dollars off for Standard users I believe.
