In principle a sensible idea to only one slot 2 TV Tuner accommodate. Fresh after the proprietary driver installation run both cards and you are actually happy. Both the supplied GlobeTV, DVB viewer and MediaPortal run well. (Of course not be used simultaneously) Of course, to such a card and record the best 2 programs at the same time on different transponders. After a few days and several programmed recordings of 2 Tuner suddenly is gone (sometimes both). But has nothing to do with the cable connection or the LNB. Because it changes - after a PC reboot is suddenly the other tuner off. Remedy (a few days) brings you to reinstall the driver through the DevManager specially supplied. It operates at the same time plus a DVB-C card of the same company as one encounters in the interaction of 2 cards (3 tuners) to even greater driver problems. Are currently used driver version 7146 and 7160 (1.3.1018.0 from 18.08.2010). A driver update is carried out, in my view too seldom. Occasionally you can under Windows 7 64 bit a Bluescreens NxpCap64.SYS shutdown condition.
2 stars because I still have a Hofnung Treiberfix gehebt the problem.
