I guess this is caused by a bad signal. Or they are using a modulation that your dm800 cannot handle very well.
Tandberg is using standard CSA, there is no reason why your dm800 should not be able to handle it.
Power3u works fine I had 9db for Wimbledon I noticed there's a lot going on in the logs plus the secs next to Oscam-emu was increasing all the time, I think it's as Kebien says au is enabled so how do I disable this?
