My coworker is in the market for a Tivo/PVR setup. He is a big football fanatic. He of course is tired of the VCR recording. His questions are 1) What PVR system offers the most Hard drive recording space and 2)What methods exist to maximize recording capacity. (i.e. Should he connect a DVR to the Tivo to offload some of the games he records and relieve space on the PVR hard drive. Importantly, is this possible? What are the common practices of Tivo Users. All ideas welcome. and cost is not a factor.
