The PREVIEW has coax, ethernet, and USB ports. AFAIK
1) The coax carries MOCA network, RCN VOD, and linear TV. Most people only use this connection
2) The ethernet port is a backup shold MOCA fail. If you want to restrict viewing (in child's room) you can connect PREVIEW to TIVO QUAD by ethernet, and the child can only watch shows recorded on the DVR
3) The USB port seems to have no function as far as I can tell

Does the TiVo mini work the same way? For example can you watch either or both linear TV and RCN VOD with an ethernet connection only?
