Add Recording a TV show including cached portion

I am watching a live tv and I want to record the rest of the show.
Add a function 1- “Record This Show from now to the end”
2 - “Record This Show from start of buffer to the end”


I second this suggestion!

I also have a ChannelMaster DVR+ (CM7500) and this is a default behaviour. It will even do this if you are watching a show in cache that has already ended. I have quite often tuned to a show to watch it and then decided while watching it that I wanted to save it, so I just hit the record button and it will grab as far back as it can.
