Updated by 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?).

Updated by 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?

Any chance of getting this added to the master branch? or even better the 4.0 branch?
