I dont think the new cards are based on TechnoTrend designs.
The old Nova-S used to be a TechnoTrend DVB-S Budget.
The old Nova-S USB used to be a TechnoTrend DVB-S Budget USB(?).
The Nexus-S used to be a TechnoTrend DVB-S Premium.
The old Nova-T used to be a TechnoTrend DVB-T Budget.
Yes think its older cards, never realised until today! My Nova-s-usb (well mine till I get rid of it!) is known as a PCline usb dvn-s! Seems TT drivers are newer than Haupapuges for most of these older devices too!
