[SML] Recording video/audio

[Jeffrey Kanyuck]

Hello,
    I am looking for some input on devices some of you may like or definitely don't like. We are wanting to record events at our facilities. Our old recording set up that was thrown together for the heck of it when someone asked for it has died.
    We have a video system (without audio) that switches between cameras with an HDMI and SDI outputs, we have an audio system which we can obviously convert to pretty much any kind of connection for output you want.
    I need a device that will record the video and audio together, and hopefully be able to stream it out at the same time.
    Our events are up to 3 hours long. Yes, I know it's a lot of storage.
    We'll edit it later and market, burn to dvd's,  youtube it, etc.

Thoughts, suggestions? Things to stay away from?
