On a second computer I installed the stick with the supplied drivers and the TV software "BlazeVide HDTV Player DVB-T" (from 2006!). The installation could not be used first, the delivered serial number was used as already declared and prevented the time operation.
In an e-mail with a request for a replacement serial number was responded within 24 hours by the seller. In addition to an apology, a replacement number was provided, with which the program book now works fine.
