We have been trying to come up with a solution at work to provide streaming live TV over our LAN. We need to have 4 different channels streaming at all times.

We have been working with Windows Media Encoder/Windows Media Server and have it working to stream one channel at a time per computer. This could work but we would need four computers and that seems a little over kill to me.

I have been looking at proprietary appliances to do this for us but so far I haven't found one and the cost could be up there.

Would there be a way to get 4 PVR-250s in a box and have MythTV do this for us off one box?

I have RA22 running at home and it works great and thought I might use it here at work.

Thanks for your time

seems like you could do what you want with vlc. if you dont need channel guide or any feature provided by mythtv, all you would need is a box setup with the 250s, probalby configured ivtv drivers, and a properly configured/build vlc server

then four separate vlc commands, on per channel can start the streams. Each stream would need its own port and channel frequency parameter.

The box will need to be pretty beefy, the vlc program is CPU intensive...at least for me but I use the scaling parameters to reduce the bandwith to allow WAN streaming

here is a good place to start reading....
