I do some work with VLC running video to IPTV settop boxes(amino). It can do IGMP UDP Broadcasts, Multicasts, etc. It can do on the fly transcoding of files as well. It can also do VOD and schedule based playing. You could do just about anything with it. I have a feeling my IPTV provider uses some form of VLC. They have issues with VOD on our boxes.. so does VLC :)
