Ich habe einen Sundtek MediaTV Digital Home III an meiner Dreambox DM800hdsev2 als zweiten DVB-C-Tuner über USB angeschlossen. Leider habe ich immer wieder gestörte Aufnahmen über den Stick. Wenn man dabei das Live-Bild anschaut, sieht man, dass das Bild für Sekunden hängenbleibt, dann gestört wieder einsetzt, bevor es wieder gut weitergeht. In /var/log/messages sieht das so aus:

Die blau blinkende LED der Box blinkt in diesen Sekunden auch nicht. Es passiert längst nicht bei jeder Aufnahme, aber doch eindeutig zu oft!
Ich verwende den Treiber vom 29.12.2015 und die aktuelle Newenigma2-Version von Anfang Dezember.
Kann das ein Hardwaredefekt des Stifts sein?
Liebe Grüße
Burkhard
