The "problem" is: I once got it working. This means: I had Mediaportal 1 TV-Server running on WinXP and did a full channel scan using this piece of pity Technisat Skystar S2. This happened on two satellites. I know I am not dreaming because a have exported the channels to an xml file via the TV-Server-Configuration tool. But: Fooling around with different versions and the drivers from cd (4.5) and from the technisat-web-pages (4.6) I cannot get it to work again. Now I setup a test machine with Win7 and even tried MP 2 because XP isn't supported any more. But: At least on Win7 the card is recognized in the TV-Server-Config-GUI, regardless if I use MP1.15 or spring edition of MP2. But starting the channel scan, it runs through all transponders and finds no channel at all. The DVBviewer TE Edition which comes with the drivers has reception though. What I could repeat on my WinXP box was using MP 1.4 and running the channel scan - but the best what it finds where only HD-Channels, leaving out every SD-Channel. Someone out there having a clue how to track this down systematically?
