I don't think Tsreader supports the starbox or at least not directly. It's not listed on the supported hardware page and I see no source module to select for it when starting up tsreader. Also I believe that in the past I've seen Rod mention that the starbox wasn't supported because it doesn't provide a raw transport stream.
Anyway, if there is any hope of getting it to work with Tsreader, it would probably only be possible using the BDA driver source since there's no source specifically for the starbox and of course that would require the starboxs driver to be BDA compliant. If that doesn't work your likely out of luck. Also since Tsreader expects to recieve a full transport stream, seeing as how it's first and foremost a transport stream analyzer tool, I'm not sure how well that will work even if it does have BDA compliant drivers. Bottom line your probably better off to look at getting a different DVB-S adapter if you want to use Tsreader.
