Hi! I have WinTV Nexus-s Rev 2.1 and Technotrend Rev. 1.6 installed. The Technotrend card has a Alphacrypt modul connected. Everything run's under Debian 3.1 with kernel 2.6.12. I'am using firmware "dvb-ttpci-01.fw-261f" (2004-07-06). http://www.vdr-portal.de/board/thread.php?threadid=36143&sid=261b77b456ed15180c7df5bfdeb659ec&hilight=fink This run's fine so far for about a week or so. But after a few days I see messages of the dvb-ttpci driver in the syslog like Dec 26 11:03:01 scotty kernel: dvb-ttpci: StartHWFilter error buf 0b07 0010 0081 b96a ret ffffffff handle e0e6 Dec 26 11:03:01 scotty kernel: StopHWFilter tried to stop invalid filter ffff, filter type = 1 When such a message appears the CAM module disappears in the CAM menu of VDR and decoding of Premiere (German Pay TV) isn't possible anymore. In this case I have to shut down the computer. A hardware reset sometimes help's but if I only boot the computer the CAM module doesn't get initialized. Is there a possibility to force a reset of the CAM? Or is there something else what I can do? I have to mention that the problem also exists when I connect the CAM on the Nexus. It also exists with different firmware versions and different kernels. The firmware I'm using works better than all the other versions. Thanks Robert
