My personal opinion is FLV format is definitely the way to go. One thing you have to understand that hasn't been mentioned is that the Flash FLV format can be delivered via two separate methods.

The first, Progressive Download, can be achieved by using a simple swf file and embed the flv inside. This is a great little option for small video's that don't necessarily need to be streamed. As it sounds the files are actually progressively downloaded to the users machine and appears to stream. This of course being successful depends on the users machine and network connection speed.

The second and probably what you will need is an actual Streamed FLV via Flash's NetConnection method. You will need either Flash Communication Server to serve the FLV this way for a true stream or you can look into Red5 (open source communication server - or flash server). Using this method you can set buffer times, etc.

I would post the link but don't want to get nailed for trying to promote a product on the forum so just Google Red5.

Good luck on the massive conversion you have in front of you.
