Description

I normally use cccam on dreambox or acamd.dll on windows to request cw from my own local oscam server and the clients always seem to figure out which tiers are the correct ones and then know to request only those in future... but tvheadend doesn't seem to learn/recognise which are correct ones... every ECM request comes with 4 tier ID's, 3 of which are not valid for my card, one is...

Could you show also tvh log ? It's unclear if you use cwc (newcamd) or capmt (dvbapi).. Also, it seems specific to CA you're using (nagra?).

I'm using cwc (newcamd). Here is some more logs, matching between oscam and tvh cwc... the CA is Irdeto ... thanks for looking at it..

Thank you! That did the trick! It now requests 4 times on the first 2 CW request's. From then on it only requests the one good one.

Is there anyway to persist/cache this, even if only in memory and not to disk so that when I change back to a channel that it knows it doesn't have to rediscover the correct one to send?
