I'm going insane...

[ricouskim]

Hi, i'm sorry to ask for help here but i can't find mine anywhere...
I just bought a Hauppauge WinTV DVBS S2 HD to replace my old skystar 2. The problem is i have no signal on many transponders. With the original program: WinTV all the transponders are well scanned with signal and i have all the channels. When i plug a skystar 2 on my pc and try to scan, all transponders are scanned and all channels work. What is the problem? BDA drivers? How can I do please, I really much prefer dvb dream, I don't want to use WinTV. Any help would be really appreciated. Thanks!
