I will be living in a RV campground which as they put it has "DirecTV (Cable/satellite to air antenna)" Once I pull the RV up to the site I just use a coax cable for the direct hook up and then scan my TV through the satellite option so it can find the channels, so I will not have a Directv box. Which TIVo can work with out a tv provider card and give me the channel grid guide which looks like the Directv grid guide where you can see each channel and the next hour or so with up next programs? I think the TIVo Bolt has the grid guide I like but don't know if you need a tv provider card? I seen the TIVo Roamio but the guide I seen doesn't look like the directv guide unless there is an option to chance the live guide to grid guide? Also the campground doesn't want anyone to stream since it slows up the wifi?
