= Revision OSCam r9748, but all OSCam have this bug

= Issue Description OSCAM-dvbapi can't decoder SKY IT new pids. This is a log of SKY IT ECM PID on 'Cinema 1' channel. There are 6 ECM PID, 2 pids for each caid.

I'm using caid 09CD with dvbapi priority directive, so OSCAM try pid 2 on 09CD, it has 'found' and decode works fine.

= When the issue occurs Problem accours when OSCam got a 'not found' from a reader, DVB-API switch decoding on pid 5, it get 'found' but tv screen is black, no image and no video appears. OSCAM will keep decodidig pid 5 until has a 'found' from reader. User must zap beetween channel to bring back the channel. It's really noise. Even cccam-pure users are affected to this bug, they must restart emu to solve that.

= How the issue is reproducable Very simple, just force oscam to decode pid 5 on a channel like 'Cinema 1' putting this in oscam.dvbapi

P: 09CD

You will see 'found' from reader, but only black screen on 'Cinema 1' channel in this case.
