I've just updated the drivers to 5.0.0.12 and found in another tread an updated version of the ttBdaDrvApi_Dll.dll.
When I replace this dll with the new one, there is an error message in tvwriter.log:

12-01-2008 18:36:48 TechnoTrend:loaded ttBdaDrvApi_Dll.dll
12-01-2008 18:36:48 Technotrend: card detected type:1
12-01-2008 18:36:48 Technotrend: unable to get proc adress of bdaapiOpenHWIdx

The same error I get with every other ttBdaDrvApi_Dll.dll, i.e. from TTMediaCenter or Sceneo.

Please help getting this work, I hope to solve some decoding issues of scrambled channels.

Thnx
