I had the Mini and the Premiere 4 hooked up via a MOCA adapter. It worked fine. I love the Mini by the way. I was going to cancel my old HD TIVO. But the rep talked me into a cheap plan. So I ordered another cable card from comcast, and got a cable splitter and hooked up the old Tivo. It is on the same cable outlet where the MOCA is hooked up. Unfortunately now the mini is not working anymore, and I am also not getting HD channels on the old Tivo. Is this setup even possible? I know the old HD Tivo is not compatible with the Mini, so I guess by hooking it up I disturbed the setup. Am I right? If so, is there any way to use this old Tivo? Thank you!
