An excellent device with remarkably sophisticated software
Written by Richard S from Framingham
I bought this a couple of years ago, using it with an older iMac in my media room and RCN service. Am now on FiOS, still working great. I was initially hesitant to buy, as input is component video rather than HDMI; but the result is very high quality, indistinguishable from 720 HDMI. The software is remarkably sophisticated all around, from set-up to editing to the large array of export formats. The product does what it claims.
Keep in mind that the EyeTV software is continually being upgraded: old reviews disparaging the software refer to early software levels.
