DVR storage usage of high def vs digital (non-hd)

On our whole house DVR from Cox, I have found that an hour of High Def TV takes up about 1% of its capacity. Does anyone know how much capacity/space digital TV (non-high def) will use. This could either be in percentages or how the data storage between digital and high def compare. I know digital takes less but not sure of how much.

Both HD and non-HD (SD) are digital.  Per Cisco specs for the 8700 series DVR's, a 1TB drive can hold 124 hours of HD programming.  That is consistent with your 1%.  The same 1TB drive will hold 560 hours of standard definition programming.  That leads to a ratio 4.5:1.  Of course, these are specs / averages, YMMV but the ratio should be close.

On the front it has Cisco HDTV cable Explorer 8642HDC. It is the one distributed by Cox 2-3 years ago when they came out with the Whole House DVR product in Omaha.
