Video Streaming Software

[TekZone]

Hello everyone,

I am totally new to the video streaming community not to the streaming community as I have done some audio streaming. I am terribly sorry if this is a stupid noob question that has already been asked half a million times but I have not found an answer in your forums.

I am looking for a stream management software. Let me explain. I would like to have several video sources: TV Tuner, Video Input (TV Card) and DV Camera (at least two). I would like to be able to switch in between both sources as easily as possible and be able to see what's showing on both sources on my monitor at the same time.

I have yet to find software which allows me to do this. I have taken a look at RealNetworks RealProducer but that only allows for a single source at once.

Thank you in advance for your help,

Antoine
