xyf:
Yeah i dont havea hdhomerun but it looks like the device to get. You can even link it to googles own live channels app although not sure if there would be any guide.
Speaking from experience (MiBox + HDHomerun), the LiveChannels app does have a guide. Not sure where the data came from, when I was playing around with the MiBox on a different network (without the hdhomerun) it wasn't there, but when I took it home and started it up, the app popped up on the homescreen from what I can recall (maybe after installing the HDHomerun app?).
