Is there an upgraded DVR that is not X1??

I had seen advertised, and told by local Comcast service center, that there's a DVR offered now by Comcast which allows recording more than 2 programs at once (and you can watch another program) -- i.e., much better than original DVR, closer to what the satellite companies are offering.**** But this is NOT the more expensive X1 set-up.**** We've been on a waiting list forever.**** Does anyone know anything about this option?
