Anyone using this combination? I know the XBox One has an HDMI passthrough, which I'd have to use if I don't want to get an HDMI switch (and if anyone has one they recommend, I'd love to learn about it) for my TiVo. I have 3 HDMI ports on the TV in question, and have the PS4, a PS3, a TiVo Roamio, and now the XBox One. Should I try to do the passthrough thing, or simply use the XBox One as a pure gaming console, and leave all TV stuff to the TiVo, and get an HDMI switch? Thanks!
