I recently purchased a 24" iMac. The main reason for the 24" monitor was to be able to watch HD TV on it. I also have a TiVo and am contemplating the purchase of their Series 3, HD-ready box. (I have lifetime service and can transfer it if I act now.) I do not own a HD TV set; I wish to take a signal from my HD TiVo and send it to my iMac, where I can enjoy HD-land. I can find no viable solution. Why is it so hard to find a way to watch a high-def TV signal on my new iMac? What am I missing? I have investigated EyeTV, and have had many discussions with Mediacom (my cable provider) and TiVo.
