That's an interesting product. It only runs on powerful PC. If it can only encode as a single stream, you can push the content to big screen TV as well. But then, that's what 4SeTV is doing in $99 box.
It is PIP but much better. PIP was good idea except remote control was pain and didn't like PIP covering part of main screen. 4SeTV solve this issue and doing 4 programs. Yesterday was perfect day for it. There were 2 college football games, tennis match and MLB at same time!
