Hello pensas08! Please try following, it works since DVBViewer Pro V5.2.7: Copy your TbsCIapi.dll (V 1.0.1.8) AGAIN into DVBViewer program directory and rename it to TbsCIapi1.dll - as result you have 2 DLL-files in this directory (TbsCIapi and TbsCIapi1). Remark: both files must be the same version...
