No, it has nothing to do with one or two stutters after a channel 
change, that's normal. This is about continuous stuttering that occurs 
every second or so and is very slight but enough to be annoying. The 
console is filled with messages about prebuffering pauses.

For me this only happens after a certain time, never in the beginning of 
a recording.

CPU usage is low enough (mostly around 30%) so that should not have 
anything to do with it.
