Considering mini for roamio basic.

Just set up basic roamio and so far so good. I'm considering grabbing a mini. I tried to read through the Moca thread but it just seems complicated. I have Ethernet on the other side of the room so I will probably just run a cat5e along the floor around to the mini until I can run a permanent line in the attic. If I go this route I won't need Moca, right? :o



So, the mini will have power, hdmi, and a cat5 connected to the back. Will it need the regular coax connected? I've looked at some guides but couldn't see it although I am y be missing the obvious.



IS there a delay in changing channels on live tv?



How about on demand? Can I get on demand to work on the mini?
