Hallo,
auf meinem Shuttle XS (genauen Typ weiss ich gerade nicht, auf jeden Fall mit NVidia ION) treten scheinbar alle 63 Sekunden Framedrops auf. Die folgenden Ausgaben sind von einem Playback mit mplayer direkt aus der Devicenode (mit TVHeadend + XBMC sind die Drops deutlich länger).
Woran kann das liegen?
