Hello Klaus,
I am using a Siemens DVB-s 1.3 as primary card -- didn't see such a behaviour before... CPU load is going up in "pushes", according to what I see in xosview. It is not that much important, just my "mencoding" processes take a longer time.On my AMD K6/II 450 replay consumes just a few (some 1..5) percent of CPU. Are you using a full featured DVB card for replaying or athe DXR3 plugin?
