Ist das normal?

[fatzgenfatz]

Hallo,

ich habe hier einen vdr (yavdr 0.3) mit einer PCI-DVB-C Karte und einem Sundtek MediaTV Pro Stick.
Als Treiber verwende ich den von yavdr bereitgestellten (yavdr-hardware-sundtek).

Prinzipiell funktioniert alles einwandfrei, aber manchmal wird das Signal am Sundtek-Stick zunehmend schlechter. Signalstärke und Rauschabstand gehen immer weiter runter, bei ca. 40% bekomme ich dann kein Bild/Ton mehr.

Wenn ich dann mit der PCI-Karte auf den Kanal schalte zeigt mir die Signalinformation Werte um die 100% an und alles läuft wie gewohnt.
Nach einem oder mehreren Reboots funktioniert dann auch der Stick wieder wie gewohnt.
Ich konnte leider keine Systematik herausfinden wann genau das passiert. Ich habe auch den MediaTV Pro Stick versuchsweise gegen einen MediaTV Digital Home ausgetauscht, dort konnte ich dieses Verhalten aber nicht beobachten. Allerdings weiß ich nicht, ob ich lange genug darauf gewartet habe.
Nachtrag: Das Verhalten tritt mit dem Digital Home Stick auch auf, die Hardware dürfte also in Ordnung sein.

Die mediaclient.log zeigt folgendes an:

Allerdings frage ich mich, ob die vielen Logeinträge in der mediasrv.log normal sind. Auch wenn ich nicht umschalte erscheinen dauernd neue Logeinträge:

Und so geht das dann ewig weiter. Die Logdatei ist schon 44Mb groß (vom 16.11. weg)

Gibt es eine Erklärung dafür?

[Sundtek]

passiert dies bei Ihnen mit jedem PC? Es ist definitiv kein normales Verhalten, irgendetwas muss wohl eine Störung verursachen (irgendwelche andere Komponenten in Ihrem Setup?)

[sundown]

Kann das Problem bestätigen, bekomme es in der Regel aber auch mit umschalten wieder weg(Denke ich zumindest).

Log poste ich sobald es wieder auftritt.

[fatzgenfatz]

Ich habe jetzt den aktuellsten Treiber installiert und werde beobachten, ob das Problem wieder auftritt.
In meinem Rechner steckt ansonsten nichts besonderes:
POV-ION 330-1 Mainboard
Cynergy 1200 DVB-C
Smargo
SDC Megtron LC-Display
Atric Einschalter.

[Sundtek]

Die Signalstärke bleibt auf jeden Fall vom Gerät her im Normalfall stabil.

[fatzgenfatz]

Kann das Problem bestätigen, bekomme es in der Regel aber auch mit umschalten wieder weg(Denke ich zumindest).

Wenn ich umschalte funktioniert es wieder ein paar Minuten, dann wird das Signal wieder schwächer.
Was kann ich noch unternehmen um dem Problem auf den Grund zu gehen?
