Before buying I had let myself be inspired by the reviews of the buyer. Due to lack of availability of the Terratec HTC I had acquired the TerraTec H5. My system: 2.27 GHz; 4GB; Vista 32 SP2; Installation: There were included 2 CDs, 1. Terratec Cinergy I3 with "TerraTec Home Cinema Basic" and 2. Terratec PI1 with "TerraTec Home Cinema" - the packaging of this CD contains a program key for "Eye TV Lite". About the order / use the individual CDs no evidence has been provided by the manufacturer. The installation was carried out by trial and error. The first CD contained no relevant for the H5 driver, only the 2 CD I had the H brought 5 Stick to run. The first CD is believed to contain a newer version of "TerraTec Home Cinema". Entering Product Key during the installation on a PC can also irritate a little, at the "Eye TV Lite" is a MAC program, you should on the PC therefore skip this procedure. Search program runs smoothly, but takes a little time. DVB-T: with the supplied antenna could be found about 12 programs. DVB-C: a fair amount of digital TV and radio programs have been found easily. Analog: all that can be received by cable, was also found. Use and reliability: after an initial crash (you should indicate the computer after the installation reboot) everything runs problemloss, rare misfires (about 0.5 seconds - probably wg processor utilization - Vista disease.) While emitting one can forgive. The received HD broadcasts can be very significant differences from the analog television detect. The image quality is very good, with HD 5.1 Soundsignal- a real cinema experience! . The keyboard between the digital channels takes about 2 to 3 seconds, ZW analog immediately when to digital or vice versa jump from analog -. Up to 6 Sec. Conclusion: very good hardware, good-to-use and robust software, therefore clearly emfehlenswert! Review: - Installation little irritating wg. lack of description of the CDs and the incomprehensible program key input + Establishment of programs + Easy to use software + Running mostly stable (even) under Vista + Quality
