My mythtv backend has two identical Technisat Cablestar 2 DVB-C cards. The problem seems to be that mythtv can only use one of them.

In mythtv-setup's channel editor I can scan channels if I use card #0. With card #1 the scan freezes showing 3% progress.

I've tried configuring the cards to use either same or separate video source. This makes no difference.

After setup I'm able to watch LiveTV and record programs as long as the system uses card #0 for those tasks. If I try to change cards during LiveTV, screen goes blank and after a few seconds I'm dropped back to main menu. Recordings using card #1 fail.

I've also tried two simultaneous recordings. The one using card #0 succeeded, the other did not. Both recordings are visible in the list of recordings (in Media Library -> Watch Recordings) but when I try to watch the one made using card #1 I get "File for the recording not found" -alert.

I'm able to tune channels with czap using either card, so it seems that cards and dvb-drivers are working.

I've tried SVN revisions 81** - 83**, updating every now and then.

Backend log of the two simultaneous recordings is can be found at
http://neuvo.ton.tut.fi/~filou/mythbackend.log_1

(failed) recording with card #1 was scheduled to start 17:45 and (succesfull) recordig with card #0 at 18:00. The first ended somewhere around 18:15 and the latter around 18:10.

My apologies for the size of the log, I don't know which verbosity levels would be essential to properly debug these problems so my backend has been running with "-v all,nodatabase". If someone told me which levels to use I would be more than happy to provide better logs.
