Question: Let's say I am watching a show from its beginning but I am not recording it. Halfway thru the show I decide I want to keep it for future viewing by hitting the RECORD button. With my old SD TiVO I had the option to record from that point on or from the beginning of the show (which was still held in a buffer). I seem unable to locate the option to record the show from the beginning with my 622. Is this true or am I simply missing something? I simply don't see an option giving me this choice.
