@Wumbel:

I got a Hauppauge NOVA-SE2 witch i think is the same Model as the NOVA-S-Plus (without Hardware Mpeg).

Well, i dont know if this works for you (but it worked for me):

Install the newest BDA-Driver from Hauppauge (http://hauppauge.lightpath.net/de/88x//88x_2_117_24275_1_whql.exe).

Open ...
