Hello, I got a Technisat Airstar 2 DVB-T PCI Card running in my PII 400 MMX with kernel 2.6.10 and vdr 1.3.17 together with the dxr3-plugin 0.2.3-pre2. Here's my problem: I measured 5V DC on the antenna input of my Airstar 2, which makes me believe that it is configured for the use with an active antenna. As I read, active antennas can lead to worse quality if they are used in regions where the signal strength is quite strong enough for passive antennas. So I got a passive one, but now I have to turn the 5V DC off. I'm studying computer science so i'm a bit experienced in programming. I - of course - searched the internet and looked in/changed various kernel modules (skystar2, mt315, mt352, stv0299) but didn't manage to turn it off. I read parts of the DVB-API documentation as well, but all I found were functions concerning the power of LNBs. Could someone tell me how to turn the 5V DC off? Is it even possible? Thanks for your help! Sebastian
