Thank you for your reply Loadlinx,

But I also think that FFMPEG is not the tool for streaming channels. As I
stated at my previous mail, I'm using szap to pass stream to FFMPEG.

I also used mumudvb and took a look at dvblast. But their common trait is
they process the stream and serve it through UDP. I wonder if it's possible
to send multiple channel streams to the driver as FFMPEG can receive
streams from driver directly.

Do I want so much thing?
