I did goggle OTARD and find it interesting. I need to find if I can get a southern exposure and how do I get wireless? Also, who would be the best to provide service?
Ok, looking closer I have found that this is a XG2v2-P. Does not appear to be upgradable. Researching this it seems that it is not a true DVR but a Cloud DVR. Unable to find a better DVR.
You get what the local franchise offers with Xfinity DVRs. They all work more or less the same except for the capacity; either in terms of hours or the number of programs you can store.
