I have the thing plugged in and was shocked that the Mac did not say anything, because of device drivers. Come fresh from Windows and knew: It will work. So the software installed afloat and the thing was ready to send. Only just made the channel scan, which takes a little longer and then I was able to enjoy TV on the computer again. Thanks to the S2 standards, I can now also receive HD programming and without any problems. My EyeTV even receives more channels than my normal Sky receiver. Am thrilled a purchase worthwhile in any case. have to deal with all other functions not tried, but I have tried the iPhone app from EyeTV. Worked course. The streaming in wireless network works beautifully. The biggest incentive to buy, however, was that I hereby also possible to use a CI module and therefore pay-TV can receive.
