HD-PVR: 2000GB / 1.8GB per hour = ~1100 hours.
HDHomeRun: 2000GB / 7GB per hour = ~266 hours.
The HDHomeRun figure will in practice be larger than 266 since many HD
channels over broadcast ATSC (or clear QAM cable) won't use the full
available bitrate. A 5.4GB per hour bitrate equates to 370 hours, so
300 hours is about right given a typical mixture of bitrates.
Conversely, while the default HD-PVR bitrate settings produce
excellent HD video, using the maximum available bitrate will
approximately double the space used per hour.
