I get this too with my SP13000. I had presumed that this was an artifact
of the tuning process, but at lunchtime I went home and checked and
found that the choppiness disappears *instantly* if I hit Escape while
the OSD is showing. The Escape cancels the OSD which disappears
immediately, *and* the audio choppiness ceases!
I will try setting the OSD display period to something very short and
see whether the garbling stops when the OSD stops.
It appears that the OSD is overloading something somehow and the audio
handling gets shortchanged as a result.
