As the owner of a Technisat HD K2 I have to say I am disappointed by Technisat. The reasons for buying the ISIO C: - Larger hard drive (especially with the many new HD channels are sometimes scarce 160GB) - Integration of the media libraries of ARD and ZDF - Continuous shooting function Especially when one of the reasons patzt Technisat total. ZDF Mediathek can be handy with the current firmware does not use. You walk in, the navigation is but then after the first confirmation is no longer possible (no response to buttons). Oddly enough, it comes with HbbTV, however: it has programmed a consignment of ZDF HD and comes in the time in which you want to record in the ZDF media library via HbbTV this program is simply not recorded. Other recorder (such as Humax iCord Cable, to the test here I have also) can do both here and also runs the access to the library as a liquid at ISIO C. The EPG of ISIO C is simply like Technisat but functional. Sequential shooting seems to work (if you follow the instructions exactly adheres). However, I find the service at HD K2 something more user friendly. The remote control during the 500GB model seems cheap, sometimes several keystrokes are needed to initiate a response. The picture quality is ok, although I 1080P compared to Humax iCord Cable (the only 1080i can) do not really see. I find the picture on the Humax iCord Cable even a bit more harmonious and sharper. I have to order my ISIO Control Keyboard. The best stay away from that, everything very slow and the navigation so that the web browser does not work sometimes. Conclusion: I give the power back! With the latest firmware bugs me are too many included and I do not play field tester for Technisat. In 2 days I the ISIO C 2x crashed during operation. Either I keep the Humax iCord Cable (though here's the EPG standard, fills in some cases only when switching on the transmitter) or I have the 160GB of HD K2 rich.
Addendum: It has to be worth the ISIO C again a chance. The unit of the 2nd delivery no longer has these errors. HBBTV now works properly and everything runs much smoother than on the 1st unit. Whether it is or ebtl the firmware update. a hardware failure on the 1st unit was the cause, good question. Thus, increasing to 4 points.
