Beginning to think its some hardware issue. As a "workaround", if you make sure your software doesn't retune constantly, it seems to survive reasonably ok. The other one I have in my server is fine after a few weeks now I've turned off any auto EIT/signalmonitoring stuff in tvheadend. I just need to write a quick cron job to check the tuning still works. :( -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
