Tvheadend

A couple of days ago I switched to tvheadend-1392. Unfortunately I encountered some bugs of which this one is really annoying.

Sometimes it happens that after a recording has finished an other running recording gets a timeout from the CAPMT server.

As this descrambler problem is irrecoverable for tvh its quite annoying. Not only results this in a very long list of error messages there is not much that can be done then to quit the recording and restart it by hand. When I quit the recording then the same happened with another running recording.

This cascading of 'descrambler: ECM - key late (40 seconds)' errors did not continue after aborting the WDR recording and the last running recording finished normally.
Speculating about what goes wrong after a recording has finished: it looks like that the communication between tvh and oscam is broken for the recording in question. Maybe reordering of the communication links on one side is not (fully) done on the other side of the link.
I know that in the previous version of tvh (377) I used, there was a minor non-fatal EMM writing problem after removing the first recording during a multi recoding session which had to do with the fact that the EMM writing was only coupled with the first connection link on the side of oscam.
This bug however, is much more serious and I really hope it will be solved. In the mean time I have to revert back to version 377 as my recording with tvh is normally unattended.

Keep up the great work,
