I really don't see why tuning to a particular channel should speed up the initial setup of the CAM communication.

I only know that EPG scan did help, and did help every time...

But, in the meantime I've built a new vdr/file -server, and guess what... yep, the delay is gone. I have no idea what was the real fix as I've changed almost everything (except dvb-hardware):

P2-350 -> Celeron-2.5G vdr-1.3.23 -> vdr-1.3.29 linux-2.4 -> linux-2.6 dvb-20041226 -> dvb in kernel etc...

But I guess there are still some people who have the same problem. Why not add an option to VDR to allow EPG scan to start right away?

I strongly believe that the EPG scan thing was just a symptom, not the cause.

The attached patch makes VDR wait until all devices that have CAMs are ready to decrypt. With this I can start VDR right away with an encrypted channel, and it doesn't say "channel not available" any more.

Please test whether this works for you, too.
