Hi, My Airstar2 card can not tune at all when installed in my htpc. It works in my friends computer so the card should be ok (He does not have any other DVB cards installed). I have tested two Airstar2 cards with the same result. The antenna should also be ok because I have another DVB-T card installed at the same time using the same antenna and it works all the time. Hardware configuration: Technisat Airstar2 Technotrend DVB-T 1300 Technotrend DVB-S 1.6 FF with CI-interface Asrock K7S8X motherboard AMD Athlon XP2500+ cpu Nvidia Gforce FX5200 300W power supply Linux distribution: Fedora Core 2 Kernel version: 2.6.10-1.770_FC2 I have tried the modules in 2.6.10 and dvb-kernel cvs from 2005-04-09 but the result is the same :-( I get the following messages when using scan: scanning /tmp/dvb-t/se-Skelleftea using '/dev/dvb/adapter2/frontend0' and '/dev/dvb/adapter2/demux0' initial transponder 490000000 0 2 0 3 1 2 0 initial transponder 514000000 0 2 0 3 1 2 0 initial transponder 778000000 0 2 0 3 1 2 0 initial transponder 650000000 0 2 0 3 1 2 0 >>> tune to: 490000:I999B8C23D0M64T8G8Y0:T:27500: WARNING: >>> tuning failed!!! >>> tune to: 490000:I999B8C23D0M64T8G8Y0:T:27500: (tuning failed) WARNING: >>> tuning failed!!! >>> tune to: 514000:I999B8C23D0M64T8G8Y0:T:27500: WARNING: >>> tuning failed!!! >>> tune to: 514000:I999B8C23D0M64T8G8Y0:T:27500: (tuning failed) WARNING: >>> tuning failed!!! >>> tune to: 778000:I999B8C23D0M64T8G8Y0:T:27500: WARNING: >>> tuning failed!!! >>> tune to: 778000:I999B8C23D0M64T8G8Y0:T:27500: (tuning failed) WARNING: >>> tuning failed!!! >>> tune to: 650000:I999B8C23D0M64T8G8Y0:T:27500: WARNING: >>> tuning failed!!! >>> tune to: 650000:I999B8C23D0M64T8G8Y0:T:27500: (tuning failed) WARNING: >>> tuning failed!!! ERROR: initial tuning failed dumping lists (0 services) Done. If I use the femon plugin in vdr I get 99% signal strength and 0% signal noice ratio on the Airstar2 card all the time (with or without the antenna connected). The other DVT-T card and the DVB-S card works with both scan and vdr. I had an interrupt conflict when the cards was inserted in an other order and then the computer froze when loading the skystar2 module but now the cards do not share interrupts with eachother.
