I had a Tivo more than a decade ago (Standard Def) and I loved it's ability to fast forward smoothly. For example I could watch a sporting event in fast forward and still be able to actually watch the action. Every DVR I've had since leaving Tivo does not allow me to do this because the fast forward advance is very jerky. I have no idea if this is because they are different brands or because it is harder to smoothly advance HD. I am interested in switching to a Tivo Bolt (or Bol+), can anyone tell me if these will allow me to fast forward smoothly.
