Hallo,
nach viel lesen (Danke an alle, die hier viel hilfreiches gepostet haben) läuft mein VDR nun "fast" gut. Ein Problem kann ich aber leider noch immer nicht lösen.
kdvb-fe-0 erzeugt eine CPU Last von bis zu 80% bei einem 3000 Athlon
Code

Das Problem tritt immer dann auf, wenn im /var/log/debug die Meldung erscheint:

Was noch eigenartig ist, dass bei Wiedergabe von Aufzeichnungen die cx88[0]/2: cx8802_timeout Meldung auch erscheint.

Hat noch jemand einen Tipp für mich?
PS: Die Kinder wollen schon den alten Receiver wieder gggggrrrrrrrrr
