Checking back in, I bought a TiVo Roamio Pro. I decided to go for the bigger capacity box, and from what I read about the commercial skipping, it seems to only work with current network shows. Amazon had a new Pro for $448 so that sounded like a good deal. I also ordered a Mini and MoCA filter which I'll deal with once I get the Roamio set up and working. (And I figure out how it all connects to each other)
I have a hard wired router right next to the spot the Tivo is going, so I should be in good shape there.
Thanks again to all for the input. This place is a wealth of knowledge and it's filled with great members! Merry Christmas to all, or whatever Holiday works for y'all!
