Currently I live on a college campus, and our TV signal is a coax cable that just runs in the house through the wall. There is no cable box. We have 10 or so HD channels but the rest are SD. I also have a 2009 Mac Mini 2 GHz Intel Duo with 4GB RAM. Also an Apple TV2, but I doubt that will help us. I am looking for a DVR type functionality. From my research, it appears the EyeTV HD is a good bet. My only concern is our (unique??) situation of only having the coax come in, with no box or dish. There doesn't appear to be a coax in on any of the hardware I'm seeing here. Can I just use a coax to component converter to get the signal ready for the EyeTV HD? Of course I'll use an external HD. Any other suggestions? Thanks!
