Hi krmlk.
If mumudvb is transconding 4 signals, it's normal.
MOI-Pro AMD have a Quad Core processor, so, mumudvb is using 75% of one core, that's not so much.
What say "top" on top?
In my case, using a PC with desktop, web browsers and mplayer to capture stream from tvheadend:

I am not transcoding only streaming to transcode server. I have fond a way to stream per channel instead of stream all transporder. I am streaming 8 transporder (every transporder has average 4 channels) what do you think about the cpu usage?
