I love my TiVo HD 652160! I have five of them (stockpiled) on lifetime subscription with the 2TB hard drive upgrade.
My provider (WideOpenWest) fortunately has dodged the MPEG-4 low bitrate bullet that Comcast fired (which I was I left Comcast) on its subscribers.
I'll keep riding these TiVo's into the sunset, then I'll probably get YouTube TV.
