That definitely sounds odd - mythbackend runs at between 5-15% CPU usage
when capturing a single stream (on an AMD Sempron at 1GHz in low power
mode). I'd check whether you're doing commercial flagging (I've
disabled this as I find it very inaccurate and it's quick enough to stick
in cut points around the commercials later) as this'll add some load.
Cheers,
