Any hints on this one?

[EDIT2] Just changed the DD kernel modules to version 0.9.28 - same problem. It appears that the error gets triggered more often while restarting the vdr. Issuing stop and start reduces the probability but not entirely.

ddci2 is only an interface for the DD CI cards, a transport extension for VDR, if you like. This is a VDR issue introduces with VDR version 2.3.5 AFAIK. I was part of an eMail conversation between Klaus and Daniel, who found this one week ago. They are currently trying to fix that. As a quick workarround, you can set QUERY_WAIT_TIME in ci.c to two seconds.
