I had all this working about 18 months ago (have moved a couple of times since then, and don't currently have a satellite dish, but still have the tuner and CAM). I think I was using MythTV 0.20 at the time. From memory once I set up the LNB properly, everything Just Worked. I have this capture card: # lspci -v ... 04:02.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11) Subsystem: Twinhan Technology Co. Ltd VisionPlus DVB card Flags: bus master, medium devsel, latency 32, IRQ 18 Memory at fddff000 (32-bit, prefetchable) [size=4K] Capabilities: [44] Vital Product Data Capabilities: [4c] Power Management version 2 Kernel driver in use: bttv Kernel modules: bttv 04:02.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11) Subsystem: Twinhan Technology Co. Ltd VisionPlus DVB Card Flags: bus master, medium devsel, latency 32, IRQ 18 Memory at fddfe000 (32-bit, prefetchable) [size=4K] Capabilities: [44] Vital Product Data Capabilities: [4c] Power Management version 2 Kernel driver in use: bt878 Kernel modules: bt878 I've also got an Irdeto 2 CAM. Sattelite TV (smart card) provider is SelecTV (Australia). Even the subscription update works with no issues, it just sat there working continuously for about 6 months. This card is pretty old and only does DVB-S (not -S2), but that's fine for me as SelecTV doesn't do HD yet. _______________________________________________ mythtv-users mailing list mythtv-users [at] mythtv http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
